A survey of dog behavior modification practice in the UK: Who is offering it, what methods are they using and how effective do their clients perceive practitioners to be?

Thousands of dogs are relinquished each year in the United Kingdom (UK) owing to behavioral problems. Hence, there is a clear role for behavior modification therapy in the mitigation of this canine welfare risk. Since statutory regulation and a universal register of canine professionals (CPs) does not yet exist in the UK, it remains unclear who is offering such therapy, which behaviors are being treated, what types of approaches various CPs may be taking and the success (or otherwise) CPs are having. This study aimed to provide some insight into these issues from the perspective of pet dog owners (clients).An online survey of 235 participants showed that the primary reason for seeking behavior help from a CP was related to aggression, although often more than 1 issue was reported. Regardless of the behavior problem, no significant differences were found for the type of CP consulted (dog trainer vs. behaviorist). Furthermore, in the client's opinion, there were no significant differences between CP types in their ability to improve their dog's unwanted behavior. Interestingly, behaviorists were significantly more likely than dog trainers to use “reward-based” methods over “balanced training” (balanced being a mix of reward and punishment; x2= 8.226, df = 1, P = 0.004).In conclusion, in the current UK vacuum of statutory regulation, clients are just as likely to employ a trainer as a behaviorist, regardless of their dog's unwanted behavior. However, both CP types were equally able to facilitate behavior improvement, as reported by the client, regardless of the type of training methods (reward-based versus balanced) adopted. This study raises further questions to be explored including the client's opinion of the extent to which the ends (behavior outcomes) justify the means (e.g., punitive training methods which are likely to be aversive for the dog). Also, the general public's understanding of the potential welfare implications of the type of behavior modification plan they may or may not choose to follow.

The Quail Game Farming Sector in Spain.

Quail (Coturnix genus) game farms were characterised in Spain using variables related to their age, geographical distribution, farmed species, structure, size, and commercialisation, using a survey conducted on 21 farms in 2018. It was found that 38.1% of the sample represented complete-cycle farms, and 61.9%, which have no breeding flocks, undertook only the finishing phase of quail raising. The average size of the breeding flock, with regard to complete-cycle farms, was 1096 males and 3735 females, with a female/male ratio of 3.6, and 75% of these farms carried out self-replacement of breeding quails. The most farmed species was European quail (Coturnix coturnix), followed by Japanese quail (Coturnix japonica), and hybrids of both species. In addition to quail, all farms produced other gamebird species such as pheasant (Phasianus colchicus) and red-legged partridge (Alectoris rufa). The rearing phase, which began when the chicks were one-day-old, lasted 35.3 days on average (range: 25-49 days), with an average stocking density of 47.2 birds/m2 in the brooder house. The finishing phase, which was carried out in flying pens at a stocking density of 9.5 birds/m2, ended when the quails' average age was 60.5 days. All farms sold quails for release in hunting reserves (EUR 1.54 per bird) and for dog training (EUR 1.65 per bird) for almost 10 months of the year; only 62% sold quails for shooting after being thrown with an adapted clay-pigeon shooting machine (EUR 1.49 per bird). Transporting quails to their destination (95.2% of the farms) and releasing the birds in the client's hunting preserve (52.4% of the farms) were services offered by the farms, among others. The main advertising and promotional strategies undertaken by the quail game farms to gain a share of the market included maintaining a business website (85.7% of the farms) and attending game and agricultural fairs (47.6% of the farms). In conclusion, this alternative poultry sector has been consolidated in Spain, five decades since the establishment of the first game farms, and it satisfies a relevant part of the demand for quail hunting.

Physical activity and sport-specific training patterns in Swedish sporting and working trial dogs-A questionnaire survey.

To explore physical activity patterns, including conditioning exercise and sport-specific training, and management routines utilized by handlers of Swedish sporting and working dogs participating in agility, obedience, rally obedience and working trial disciplines. Dog handlers provided information on competition-level dogs through an internet-based cross-sectional and descriptive survey on physical activity, sport-specific training and management. Results are reported overall and stratified by participation in specific disciplines. We received 1615 replies to the questionnaire. After data cleaning, 1582 dogs (98%) remained for the analysis. Of these, 430 participated in agility, 790 in obedience, 596 in rally obedience, and 847 dogs had competed in a working trial, i.e., messenger, protection, search or tracking. Number of disciplines performed by each dog varied between one and five. Most common was participation in one (n = 767, 48%) or two (n = 541, 34%) disciplines. Out of the dogs competing in one discipline, 38% (n = 294) were considered to be specialized as they actively trained only that discipline for ≥10 months per year. The vast majority of the dogs (n = 1129, 71%) received more than 1 h of daily physical activity, e.g., walks, and only n = 51 (3%) were never exercised off-leash. Preferred self-selected gait was trot (n = 907, 57%) and gallop (n = 499, 32%). A fifth (n = 319, 20%) never played with other dogs. The majority (n = 1328, 84%) received more than 1 h of vigorous physical conditioning exercise per week. Almost three quarters (n = 1119, 71%) participated in physical conditioning exercise. Two thirds (n = 953, 60%) participated in at least 3 h of sport-specific training per week and only a very small portion (n = 35, 2%) trained their specific discipline less than once per week. Median total work load, i.e., all daily physical activity, vigorous physical conditioning exercise and sport-specific training, was 16.5 h per week. We observe physical activity at moderate to high durations and moderate to vigorous intensities among Swedish sporting and working trial dogs. Most dogs received physical conditioning exercise, but not all dogs were warmed up before training and competition. Our study provides veterinary professionals and dog trainers with valuable insights on the physical exposures and management routines of sporting and working trial dogs.

Internet-based survey evaluating the impact of ground substrate on injury and performance in canine agility athletes.

Agility is a rapidly growing canine performance sport worldwide, yet the literature is sparse regarding the impact of ground substrate on performance and injury. Approximately 1/3 of dogs participating in agility trials will experience a performance-related injury. The impact of ground material has been well-documented in racing greyhounds, equine athletes, and humans, but has been minimally investigated in agility dogs. In this retrospective, cross-sectional study, 300 respondents (handlers, owners, and trainers) of 308 agility dogs completed an online survey regarding their dog's training and competition regimen, history of injury, perceived association between injury and substrate and/or agility obstacle, markers of decreased performance (MDPs) observed on different substrates, and changes to routine following injury. 35.7% of dogs sustained a training injury (TI) and 11.2% sustained a competition injury (CI). The most commonly reported sites of injury were the shoulder (TI: 33.9%, CI: 25.4%), forelimb digits (TI: 14.7%, CI: 11.9%) and iliopsoas muscle (TI: 11.9%, CI: 13.6%). Dogs most commonly trained on natural grass (85.3%), artificial turf (50.8%), and dirt (34.5%). Significantly fewer MDPs were observed on natural grass than any other substrate except dirt. Significantly more MDPs were noted on rubber mat compared to natural grass, artificial turf, dirt, sand, or foam mat. Rubber mat had the highest Incidence Proportion (IP) (32.0%) of TI and was perceived to be related to TI in 87.5% of cases. Obstacles perceived to be associated with injuries included jumps (TI: 37.5%, CI: 27.8%), contacts (TI: 29.7%, CI: 22.2%), weaves (TI: 11.9%, CI: 13.9%), and tunnels (CI: 25.0%). Overall, agility dogs were perceived to perform best on natural grass and dirt, while rubber mat was associated with injury and decreased performance. Respondents were willing to make significant alterations to their dog's routine due to a perceived association between substrate, injury, and performance. Further prospective studies are needed to assess the impact of substrate composition and maintenance, and inform evidence-based recommendations to maximize performance and minimize performance-related injury in agility dogs.

Greyhound morbidity and mortality in Australia: A descriptive analysis of reported data from regulatory racing agencies.

Commercial greyhound racing is legal in Australia but controversial due to concerns around animal welfare. To make evidence-based recommendations of animal welfare standards, a comprehensive analysis of available data on race events, animal health, injuries and fatalities is required. We undertook a review of publicly available data and reports published by official greyhound racing bodies for the purpose of determining how morbidity and mortality events associated with dog training and racing could be benchmarked. 6 years of available data from stewards' reports, quarterly and annual reports were descriptively analyzed from New South Wales, Victoria and Queensland. Whole-of-life tracking for individual dogs was sparse. Although stewards' reports were published in all three states, the availability of aggregated quarterly and annual reports varied. When available these provided additional information such as injury incidents standardized per thousand starts. In Queensland, quarterly and annual reports provided an overview of greyhound mortality and morbidity rates. In contrast with Victoria, quarterly reports were unavailable and only annual reports were published, meaning quarterly trends could not be determined. Therefore, injuries categorized by severity that were routinely included in quarterly reports in Queensland and New South Wales were unavailable in Victoria. Our findings demonstrate that data recording and reporting practices must be standardized to accurately evaluate whether animal welfare standards are being met in the Australian greyhound racing industry. Our recommendation is to have national standardized reporting of injuries and deaths, and a publicly available database for whole-of-life tracking for individual racing greyhounds.

Early Locomotor Training in Tetraplegic Post-Surgical Dogs with Cervical Intervertebral Disc Disease.

Simple SummaryAcute cervical disk disease may result in tetraplegic dogs without the ability of sternal posture, which could result in aspiration pneumonia, hypoventilation and other complications. The main treatment approach is surgical, depending on the clinical sign’s severity, and early post-operative rehabilitation may also be considered, including in dogs with spinal hyperesthesia, through the implementation of locomotor training with specific guidelines in the first days after surgery. Locomotor training (LT) is task-specific repetitive training, with sensorimotor stimulation and intensive exercises that promote neuromuscular reorganization. This study aimed to observe if LT could be initiated safely in the first 3–15 days after surgery in tetraplegic C1–C5 IVDD—Hansen type I dogs. This prospective blinded clinical study was conducted at two rehabilitation centers in Portugal, with 114 grade 1 (MFS/OFS) dogs, divided by the presence of spinal hyperesthesia into the SHG (spinal hyperesthesia group) (n = 74) and the NSHG (non-spinal hyperesthesia group) (n = 40), evaluated in each time point for two weeks according to a neurorehabilitation checklist by three observers for inter-agreement relation. LT was safely applied with 62.3% of the OFS ≥ 11 within 15 days and of these, 32.4% achieved a OFS ≥ 13. There were no new cases of hyperesthesia in the NSHG and from the SHG all recovered. Comparing groups, a significant difference was observed in their ability to achieve ambulatory status (p < 0.001), between the presence of hyperesthesia and days until ambulation (p < 0.006) and in each time point (p < 0.001; R2 = 0.809). Early LT may be a safe treatment to be applied in the first 3 days on these dogs and spinal hyperesthesia should be important to the rehabilitation team. This study should be continued.

УМОВИ РЕЗУЛЬТАТИВНОГО ВИКОРИСТАННЯ КІНОЛОГІЧНИХ КОМАНД

The conditions for the effective use of Junior Canine Inspectors with service dogs of remand centers and penal institutions of the State Criminal and Executive Service of Ukraine while performing their assigned tasks are clarified in the article. The essence and content of the proposed principles of using dog commands are revealed. The basic principles of application of canine commands while performing their tasks on purpose are offered the following: – the use of service dogs, taking into account their physiological characteristics and physical capabilities; – high efficiency of dog training; – activity and timeliness of actions of canine teams during the performance of purpose tasks; – the use of dog commands in combination with technical means; – continuous improvement of training methods and tactics of cynologists’ actions with service dogs. The responsibilities of the junior canine inspector to create favorable conditions for the effective use of service dogs is clarified. Namely, they are obliged to: – to improve their knowledge, study according to an individual program and systematically train a service dog assigned to them constantly; – to be able to use a service dog in accordance with the requirements of the law; – to show determination, agility and physical endurance while performing official tasks; – to keep a diary of education (training) of a service dog; – to qualitatively fulfill the requirements for storage, keeping and feeding of service dogs; – to clean and protect the fixed dog from diseases and various injuries; – to know the most common diseases and signs of dogs, as well as ways to provide them with the first aid; – to clean the premises for a service dog, keep in proper condition and constant readiness of equipment and care items; – to report to the Senior Canine Inspector of the remand center (penal institution) about the dog's disease immediately; – to follow the rules of personal hygiene when working with a service dog. The factors that ensure the smooth operation of canine teams are proposed and the factors that affect the performance of a service dog are specified, taking into account the specifics of service activities of remand prisons and penal institutions, among which the following should be noted: – general condition of the body of a service dog; – degree of preparedness (training) of a service dog; – dog trainer’s knowledge, skills, abilities and experience to manage the behavior of a service dog during its use in specific circumstances; – odorous situation in the area (place) of a service dog use; – peculiarities of the odor trail (antiquity, wind, precipitation, atmospheric pressure); – time of the year, time of the day; – terrain (relief, vegetation, etc.); – distracting environmental stimuli. Key words: Junior Canine Inspectors, service dogs, effective use, principles, factors.

Rapid changes in profiles from stored materials used in scent training of explosive detection dogs

Canines trained on scents from materials emitting vapours of explosives and related compounds are widely used to detect explosives in civilian, military and forensic applications. Despite the importance of these training materials, there is limited knowledge on how long these subsamples can be stored and whether vapour profiles change over time. We developed a sampling methodology that makes use of a secondary chamber for stabilisation of headspace concentration to allow reliable and reproducible determination of scent profiles. The effect of aging was investigated by following the response of volatile markers emitted from eight common explosives in open and closed containers over two months or two years. The initial headspace air volume consisted of a wide variety of chemical substances related to explosives, with levels varying in magnitude from low ppb to ppm. All included subsamples were affected by aging by demonstrating exponentially lower levels, and five subsamples showed a significant change in their scent profile. The dominant components decreased on a short time scale for plastic explosives based on RDX, PETN and dynamite as well as for granules of octol and ammonium nitrate mixed with fuel. For flakes of TNT, granules of Comp B and nitrocellulose powder, headspace air concentrations declined, but the overall character of their profiles were in general more stable. The overall changes, i.e., lower levels and/or changed profiles, justifies regular checks of the scent status of training materials. Considering these results together with data displaying marginal changes in energetic performance, it is advisable to complement scent training with training materials subjected to different durations of aging.

Creating a Virtual Dog Simulation to Examine Perceived Control

Research on the topic of perceived control in caregiving is often limited in scope due to safety concerns. Two studies were done to create a simple virtual dog training simulation to have a safe and controllable way to test perceived control in both difficult and easy caregiving situations. Using materials normed in Study 1, we were able to create a simple virtual dog training simulation with 3 dog attitude levels; Friendly, Neutral, and Aggressive. Study 2 found a pattern of results that matched previous findings in perceived control research, which indicate not only further evidence on the relationship between perceived control and caregiver interactions with pets, but also the viability of using a virtual simulation to test such things.

The Welfare of Fighting Dogs: Wounds, Neurobiology of Pain, Legal Aspects and the Potential Role of the Veterinary Profession.

Simple SummaryDog fights are cruel and harmful events which have a clear impact on animal welfare. For this reason, many countries have banned these events via statute. However, in some regions of the world they are still legal. Moreover, the enforcement of legal bans can be problematic in countries where they are illegal, and they may still occur. This article provides background information on dog fighting and the welfare implications of it. This includes consideration for the pain inflicted, and its mechanisms of perception and recognition. It also analyzes the injuries and emotions experienced by the animals and considers the profile of the breeders and handlers involved in the activity. Since welfare concerns often extend beyond the animals’ fighting lives, a discussion around the possibilities of reintroduction into suitable environments for these animals is also made. Finally, attention is turned to the role that veterinarians can and should play in dealing with these issues of welfare.Throughout history it has been common to practice activities which significantly impact on animal welfare. Animal fighting, including dogfighting, is a prime example where animals often require veterinary care, either to treat wounds and fractures or to manage pain associated with tissue and where death may even result. Amongst the detrimental health effects arising are the sensory alterations that these injuries cause, which not only include acute or chronic pain but can also trigger a greater sensitivity to other harmful (hyperalgesia) or even innocuous stimuli (allodynia). These neurobiological aspects are often ignored and the erroneous assumption made that the breeds engaged in organized fighting have a high pain threshold or, at least, they present reduced or delayed responses to painful stimuli. However, it is now widely recognized that the damage these dogs suffer is not only physical but psychological, emotional, and sensory. Due to the impact fighting has on canine welfare, it is necessary to propose solution strategies, especially educational ones, i.e., educating people and training veterinarians, the latter potentially playing a key role in alerting people to all dog welfare issues. Therefore, the aim of this review is to describe the risk factors associated with dogfighting generally (dog temperament, age, sex, nutrition, testosterone levels, environment, isolation conditions, socialization, education, or training). A neurobiological approach to this topic is taken to discuss the impact on dog pain and emotion. Finally, a general discussion of the format of guidelines and laws that seek to sanction them is presented. The role that veterinarians can play in advancing dog welfare, rehabilitating dogs, and educating the public is also considered.

Constructional fear treatment: Teaching fearful shelter dogs to approach and interact with a novel person.

Of the millions of dogs that enter animal shelters in the United States each year, many exhibit behaviors labeled as fear, which can decrease their likelihood of adoption. Current dog training procedures to treat these behaviors can take months or even years to show significant change. When these procedures are used in shelters, they mainly focus on reducing fear, as opposed to teaching specific behaviors to increase adoptions. The goal of the current study was to teach fearful shelter dogs to interact with a novel person. A seven-step shaping procedure used the removal of the novel person as a reinforcer. The dogs learned a series of behaviors, starting with looking at the person and small head movements and progressing until the dog was approaching the front of the kennel and voluntarily interacting with the person. All three dogs completed the program in a short amount of time (under 40 min) and showed an increase in approaching the front of the kennel, sniffing, tail wagging, and accepting petting. These behaviors persisted during a return-to-baseline condition, suggesting that the newly shaped behaviors had come under the control of positive reinforcement in the form of social interaction with the experimenter.

Detector dog training shows companion-dogs rapidly remember the what and where of instinctively significant scents

Companion dogs with no previous experience were trained in a drug detector dog adapted method to recognise the scents of ‘prey’ animals and allowed to sleep in their natural habitat, at home with their owners. After each of two consecutive nights sleep they were evaluated on the next days. We tested their declarative memory (knowing that) and also procedural memory (knowing how), by using chase-and-fetch training and testing routines, which involved walking and running around as well as sniffing. All dogs were able to remember what their trained-for scents were and most dogs were also able to remember where their trained-for scents were against distractors. There were indications that scent memory could be reinforced and can be further learned that day. After training, when dogs were denied their day time and evening sleeps and instead provided with stimulating activities, surprisingly they still showed no ‘first-night-effect’ (of disrupted sleep and subsequent memory reduction) and successfully found their trained-for scents, which was attributed either to their robust short sleep-wake cycles, them being highly motivated and being in their natural habitat. Our evidence showed that after training (using their dominant sense of smell) our dogs showed all the aspects of sleep including both NREM and REM and demonstrated their declarative and especially their procedural memories on subsequent days. There was no significant difference in the number of sleep sessions per hour, the time asleep, the sleep session length, the percentage of time in REM or REM latency between normal day and night sleep compared with denied day/evening and normal night sleep.&#x0D; These findings provide a further indication of dogs’ sense of self when applying the same criteria for humans. There was a sign that REM sleep in old dogs is not reduced when they are monitored at home. We believe that it is possible for companion dog owners whose dogs’ enthusiastically fetch, to readily train their own dogs by this method

Retrospective Examination of Service Dog Training Program Participation and Mental Healthcare Utilization

ObjectiveTo investigate the association between Service Dog Training Program (SDTP) participation and mental health care utilization. DesignRetrospective cohort study. SettingOutpatient rehabilitation clinic at a large military treatment facility. ParticipantsMilitary Health System beneficiaries who attended at least 1 SDTP session at a large military treatment facility (N=597). SDTP program enrollment records identified participants. InterventionThe SDTP, a unique application of animal-assisted therapy, is intended to improve the mental and cognitive health for individuals with war-related trauma. Main Outcome MeasuresNegative binomial regression calculated the associations between the SDTP participation rate and 2 mental health care utilization outcomes: mental health encounter days and psychotropic medication months’ supply. ResultsMost of the 597 participants were male, enlisted service members, and aged 25-34 years. Approximately 46% had a posttraumatic stress disorder diagnosis, 21% had a traumatic brain injury diagnosis, 47% had an opioid prescription, and 58% had a sleep aid prescription pre-SDTP participation. Participation was categorized into low (≤1 sessions), medium (>1 and ≤2 sessions), and high (>2 sessions) monthly participation. In adjusted analysis, high monthly SDTP participation was associated with 18% fewer post-SDTP mental health encounter days (rate ratio [RR], 0.82; 95% confidence interval [CI], 0.68-0.96) than low monthly SDTP participation. High monthly SDTP participation was also associated with a 22% fewer post-SDTP psychotropic prescription months’ supply (RR, 0.78; 95% CI, 0.64-0.95) than low monthly SDTP participation in adjusted analysis. ConclusionsResults suggest that participants who attend more than 2 SDTP sessions monthly encounter mental health care differently post SDTP than participants who attended 1 or fewer monthly sessions. Adjunct therapies, such as the SDTP, may offer patients a nonstigmatizing way to engage in mental health care.

Genetic Diversity of Babesia canis Strains in Dogs in Lithuania.

Canine babesiosis is an emerging and rapidly expanding tick-borne disease in central and northeast Europe. In the last two decades, the endemic area of Babesia canis has expanded from central Europe to the Baltic region. This study aimed to investigate the genetic diversity of B. canis strains isolated from naturally infected dogs in different regions of Lithuania using PCR-RFLP and sequence analyses based on a partial region of 18S rRNA and Bc28.1 genes. Blood samples from 149 dogs suspected of having babesiosis were collected in Lithuania during 2016–2017. Based on PCR-RFLP profiles and two nucleotide substitutions observed in 18S rRNA gene sequences, three B. canis genotypes were identified in Lithuania—18S rRNA-A, 18S rRNA-B and 18S rRNA-A/B—with the A/B genotype predominating (83.9%). Based on the obtained PCR-RFLP profiles of the Bc28.1 gene, four B. canis genotypes were identified: Bc28.1-B (53.8%), Bc28.1-34 (20.8%), Bc28.1-A (17.9%), and Bc28.1-34/A or B (7.5%). Sequence analysis of the partial Bc28.1 gene revealed eighteen polymorphic sites and thirteen sequence variants among the Lithuanian samples. The B. canis genotypes obtained were detected with varying prevalences in different regions of Lithuania.

Validating the Use of Amputated Limbs Used as Cadaver Detection Dog Training Aids

Cadaver detection dogs (CDDs) are trained to locate human remains and/or objects associated with human remains. This is possible due to their extraordinary olfactory capabilities compared to those of humans. To reinforce this capability, CDDs must be trained and regularly exposed to the target odor in the form of training aids which include—chemical formulations, animal remains, and/or human remains. Currently, the Ontario Provincial Police (OPP) use amputated limbs/feet from consented surgeries performed on diabetic patients as cadaver detection dog training aids. There is limited knowledge about the volatile organic compound (VOC) composition of these training aids and their appropriateness as an alternative to human remains for CDD training purposes, which formed the aim of the current study. VOCs were collected from amputated lower limbs/feet repeatedly using thermal desorption (TD) tubes and analyzed with comprehensive two-dimensional gas chromatography—time-of-flight mass spectrometry (GC×GC-TOFMS). The response of cadaver detection dogs to these training aids was also recorded to understand their alert in the context of the detected VOCs. VOC classes including acids, alcohols, aldehydes, ketones, ester and analogues, ethers, aliphatic, cyclics, sulfur-containing, nitrogen-containing, and halogen-containing VOCs were identified. Of these classes, cyclic VOCs were most abundant followed by nitrogen-containing VOCs while ethers were the least abundant. The most prominent VOCs identified in amputated limbs/feet were decomposition related however, one VOC—sevoflurane, originated from anaesthesia during the surgeries. It was determined that the VOC profile of aged and relatively recent training aids were variable. The aged training aids sampled over time had less variability (compared to more recent training aids). Additionally, the VOC profiles of samples was not found variable owing to the storage conditions—room temperature, refrigerator or freezer. Overall, a 98.4% detection rate was observed for amputated limbs/feet used as CDD training aids and the presence of non-decomposition related VOCs such as sevoflurane did not appear to impact the CDDs’ detection capability. This study highlights that the presence of decomposition VOCs in amputated limbs/feet and their high detection rate by CDDs validates their use as alternative CDD training aids.

The Potential Impact of a Dog Training Program on the Animal Adoptions in an Italian Shelter.

Simple SummaryHuman–dog relationships are mainly focused on the physical and emotional wellbeing, and has much evolved in the last decades, becoming even more intense over time. Such a novel conception should also be applied to the life that takes place in kennels, which have been mistakenly regarded as a landfill or a burden on society for too many years. Here, we took into consideration an Italian shelter, and analyzed 555 adopted dogs who underwent a well-detailed behavioral training program, to assess the potential impact of the education upon the adoption of attitude. We documented a higher increase in the number of adoptions both for adult and senior animals when compared to the age-matched untrained dogs. Collectively, our data highlight the importance of a proper training, mainly accomplished with reward methods, to get a more suitable and balanced owner-dog attachment.One of the main concerns of the human–dog relationship is today associated with the quality life inside the kennels, which are very often regarded as animal dump where dogs are exiled, representing a burden on society. In the present study we sought to investigate the importance of performing an appropriate behavioral program on the adoption chances within an Italian shelter, near Naples (Ottaviano). In this respect, we enrolled 555 adopted dogs of different ages, who followed a tailored-4-month lasting training program between 2018 and 2020. Once entered there, they were carefully examined by the veterinary behaviorist, and directed towards a suited training program, to improve living conditions. We documented a higher number of both adult and senior dogs who left the kennel and were adopted, compared to the age-matched untrained animals (n = 479), housed in the same kennel from 2015 to 2017. Taken together, the present data highlight an important role for training in improving the natural attitudes of the companion dogs, thus pointing towards a better human–animal bond.

A Prospective Cohort Study Investigating the Behavioural Development of Bitches in a Guide Dog Training Programme Neutered Prepubertally or Post-Pubertally.

There are few studies that investigate the effect of neutering bitches before or after puberty. The majority of current literature examining the impact of the timing of neutering on health and behaviour has used age rather than the onset of puberty as the key variable. The aim of this prospective cohort study was to investigate the effects of timing of neutering in relation to puberty on behaviour in female dogs reared and trained in an assistance dog programme. The study examined data for bitches neutered before or after puberty to compare scores for six behavioural factors (training and obedience, aggression, fear and anxiety, excitability, attachment and attention-seeking, and social behaviour) measured at 1 and 3 years of age. Labrador and Golden Retriever crossbreed bitches were neutered before (n = 155) or after (n = 151) puberty. Neutering before or after puberty had no impact on mean scores for the six behavioural factors at 1 or 3 years of age. When examining the change in behavioural factor scores between 1 and 3 years of age, only aggression behavioural factor scores were influenced by neutering before or after puberty. Bitches neutered after puberty were less likely to have aggression factor scores that increased between 1 and 3 years of age (OR = 0.959, 90% CI = 0.924 to 0.995, p = 0.06). However, the majority of bitches scored “0” for aggression at both time points (indicating no aggression behaviours were observed), and the number of bitches for which scores increased between 1 and 3 years of age was low (before puberty = 20, after puberty = 9). This is consistent with very mild aggressive behaviours being observed in a small number of animals and is, therefore, of questionable concern. The results suggest that, for Labrador and Golden Retriever crossbreed bitches, neutering before or after puberty has little to no effect on future behaviour. It is recommended that decisions about the timing of neutering are not informed solely by impacts on behaviour, but that they also consider evidence relating to the impacts on bitch health and well-being.

Effects of Thyroidal Disturbance on the Behavior of Domestic Dogs (Canis Lupus Familiaris)

Hypothyroidism is not uncommon in dogs, but it is actually very often diagnosed in elderly dogs. When and how does the disease start? What are the first recognizable signs? The first symptoms are usually changes in the behavior. First, these changes are quite subtle, but as the illness progresses, they can get very grave. We do often hear from the worried owners, that their report of a behavioral change to their vet is often ignored, not taken seriously or simply interpreted as unsteady or insufficient dog training/ education. This not taking seriously of the first signs is very concerning and a big problem in many ways. It is delaying the finding of the right diagnosis and treatment, which leads to suffering of the animal and the owner. In some cases, it leads to giving the dog up as an unbearable danger to the family. So the dog, who is only ill and could be back to normal with the right medical treatment, and finally ends up in a dog shelter or a new family. The common understanding is, that hypothyreoidism is an illness solely occurring in the elderly dog. In contrast to this, the authors found out, that thyroidal problems occur already at relatively young ages. This is a very important finding, considering that many clinically practising veterinarians expect hypothyreoidism only in the aged or elderly dog and will not run any diagnostics in relatively young or middle-aged animals. The authors also found significant differences in the personality traits of emotional stability and extraversion. Therefore, we would like to expand the existing studies, so that this widely underestimated topic finally comes to the fore and hopefully, in the future the right diagnostcal steps can be taken at an early stage of the disease.

Head-mounted mobile eye-tracking in the domestic dog: A new method.

Humans rely on dogs for countless tasks, ranging from companionship to highly specialized detection work. In their daily lives, dogs must navigate a human-built visual world, yet comparatively little is known about what dogs visually attend to as they move through their environment. Real-world eye-tracking, or head-mounted eye-tracking, allows participants to freely move through their environment, providing more naturalistic results about visual attention while interacting with objects and agents. In dogs, real-world eye-tracking has the potential to inform our understanding of cross-species cognitive abilities as well as working dog training; however, a robust and easily deployed head-mounted eye-tracking method for dogs has not previously been developed and tested. We present a novel method for real-world eye-tracking in dogs, using a simple head-mounted mobile apparatus mounted onto goggles designed for dogs. This new method, adapted from systems that are widely used in humans, allows for eye-tracking during more naturalistic behaviors, namely walking around and interacting with real-world stimuli, as well as reduced training time as compared to traditional stationary eye-tracking methods. We found that while completing a simple forced-choice treat finding task, dogs look primarily to the treat, and we demonstrated the accuracy of this method using alternative gaze-tracking methods. Additionally, eye-tracking revealed more fine-grained time course information and individual differences in looking patterns.

Distribution and diversity of dog parvoviruses in wild, free-roaming and domestic canids of Newfoundland and Labrador, Canada.

Some parvoviruses of carnivorans can infect multiple host species. Since many canine parvoviruses were only discovered recently, their host-range is still unexplored. We examined the host distribution and diversity of five dog parvoviruses in four canine populations from Newfoundland and Labrador, Canada, and investigated the potential for these viruses to cross the species barriers. Canine bocavirus 2 (CBoV-2) and the minute virus of canines were detected in stool from free-roaming dogs from Labrador (5/48 [10.4%] and 3/48 [6.3%], respectively) and two different CBoV-2 variants were identified. Canine bufavirus was identified in stool from free-roaming dogs (1/48, 2.1%) and foxes (3/80, 3.8%) from Labrador, but two different variants were observed in the two host species. The variant found in foxes was highly divergent from previously identified strains. Two cachavirus 1 variants, genetically similar to those circulating in other Canadian wildlife, were found in spleens from Newfoundland coyotes (3/87, 3.5%). Canine parvovirus type 2 (CPV-2) was found in stool from free-roaming dogs from Labrador (2/48, 4.2%) and in spleens from Newfoundland coyotes (3/87, 3.5%). Comparing CPV-2 sequences from these hosts to those retrieved from local symptomatic domestic dogs revealed the presence of a highly heterogeneous viral population as detected strains belonged to five different clades. The close relationship between CPV-2a strains from a dog and a coyote suggests the occurrence of viral transfer between wild and domestic canids. The identification of highly related strains with a similar molecular signature characteristic of older CPV-2 strains in free-roaming and domestic dogs suggests a probable common ancestry and that older CPV-2 strains, which have not been identified in dogs since the 1990s, persist in this part of Canada. Follow-up studies should evaluate samples from a larger number of animals and host species to extensively investigate the possible occurrence of cross-species transmission for recently discovered parvoviruses.
