The impact of training method on odor learning and generalization in dogs (Canis lupus familiaris).

Detection dogs are required to learn and alert to multiple different odors during training and to generalize this learning to similar odors when working. They should be both sensitive to variation in the target odors and specific enough to avoid false alerts, but how readily they achieve this is likely to depend on the training method employed. The majority of agencies train by presenting single target odors in isolation, and adding additional odors consecutively, although recent research with rats suggests intermixing the target odors concurrently throughout training may be a more effective approach. This study therefore tested the relative efficacy of intermixed training in dogs. Using an odor-detection lineup, pet dogs were trained to detect two target odors, A and B. Those allocated to the "sequential" group were trained to criterion on odor A and then trained on odor B (or vice versa), the "compound" group were trained on a mixture of AB, and the "intermixed" group trained on A and B concurrently. Each dog was then tested on all combinations of the test stimuli (A, B, and AB), as well as combinations containing a novel interferent (AC, BC, and ABC). Results revealed that dogs trained by the intermixed method made significantly more correct (true positive) indications, and significantly fewer miss (false negative) indications than the other two methods, suggesting that intermixed training is more effective than currently used alternative training methods. Thus, for improved performance and generalization, we recommend detection dog training should use an intermixed method of training. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Influence of biotic and abiotic factors on the performance of service dogs of different genotypes

Aim. In the current situation of Russia's military invasion of Ukraine, national security, territorial integrity and state sovereignty are extremely important for the country's dog services. The benefits of using dogs are much greater than the costs of their maintenance and training. Dogs search for explosive devices, missing soldiers and their remains, detain criminals, and guard military facilities. Different breeds of service dogs are preferred for each special task. Purpose: to study the methods of training service dogs of different breeds of detection service by scent trail and to analyse certain factors affecting the quality of the dog's work. Methods. The research on the topic of the scientific work was conducted in the conditions of the dog training center of the Ministry of Internal Affairs of Ukraine in Vinnytsia region. The following methods were used in the research process: zootechnical, analytical, calculation, biometric. The research materials were used for the study of German Shepherd, Labrador Retriever and Rottweiler dogs, which underwent a general training course and special training for detective work on human scent trails. Results. Service dogs have been used in human life for centuries to protect important facilities and territories, mine clearance, customs service, detention of criminals, search and rescue of people. Training of different breeds of dogs for a particular type of activity, painstaking and careful work of dog handlers, on which the results of dog performance in different conditions of their use depend. Conclusions. The testing of sniffer dogs for human scent detection was carried out in accordance with the existing rules and methods used in the dog training centers of the National Police of Ukraine. The conditions of keeping and feeding the dogs met the standards and recommendations, taking into account the breed, age, live weight, specifics of work and workload, which allowed us to obtain reliable results in the experiments. In the organisation of training and coaching of service dogs, all our studied factors will help dog handlers to use the dog methodically and competently in real circumstances.

Antibiotic resistant Escherichia coli strains inhealthy pets from Tamaulipas, Mexico.

Antibiotic resistance constitutes a significant public health challenge, with diverse reservoirs of resistant bacteria playing pivotal roles in their dissemination. Among these reservoirs, pets are carrying antibiotic-resistant strains. The objective of this study was to assess the resistance profiles of Escherichia coli, and the prevalence of extended-spectrum β-lactamase (ESBL) producing E. coli strains in dogs and cats from Tamaulipas, Mexico. A total of 300 stool samples (150 dogs and 150 cats) from healthy pets were subjected to analysis. Antibiotic susceptibility testing and the identification of ESBLs were carried out by disc diffusion method. The presence of resistance genes, class 1, 2, and 3 integrons (intI1, intI2, and intI3) and phylogroups was determined by PCR analysis. The findings reveal that 42.6% (128/300) of the strains exhibited resistance to at least one of the eight antibiotics assessed, and 18.6% (56/300) demonstrated multidrug resistance (MDR), that distributed across 69 distinct resistance patterns. Altogether 2.6% of E. coli strains (8/300) were confirmed as TEM and CTX-M type ESBL producers. These outcomes underscore the roles of dogs and cats in Tamaulipas as reservoirs for the dissemination of MDR and/or ESBL strains. The results underscore the necessity for conducting prevalence studies on ESBL-producing E. coli, forming a foundation for comprehending the present scenario and formulating strategies for the control and mitigation of this issue.

PSIX-10 Effects of Bacillus subtilis ATCC PTA-122264 on macronutrient digestibility and fecal characteristics, metabolites, and microbiota of healthy adult dogs subjected to an abrupt diet change

Abstract Probiotic use in dogs is increasing, with spore-forming Bacillus species gaining interest due to their viability during processing, storage, and in the gastrointestinal tract. B. subtilis is known for its adaptable metabolism that may be useful in pets subjected to abrupt dietary changes. The objective of this study was to determine dietary apparent total tract macronutrient digestibility (ATTD) and fecal characteristics, metabolites, and microbiota of healthy adult dogs supplemented with B. subtilis ATCC PTA-122264. All procedures were approved by the University of Illinois IACUC prior to experimentation. Dogs [n = 12; 6 ± 1 yr; 8.71 ± 0.91 kg body weight (BW)] were used in a replicated 3x3 Latin square design (n = 12/group) and fed to maintain BW. In each 42-d experimental period, dogs were allotted to one of three treatments: Control (kibble diet only), Low [kibble diet + 1×109 colony-forming units (CFU) of B. subtilis], and High (kibble diet + 5×109 CFU of B. subtilis). After a 22-d adaptation phase, a 5-d fecal collection phase was followed by a blood collection phase. On d 28, dogs were abruptly changed to a canned diet and fed for 14 d, with fecal samples collected on d 30 (2 d post change), 34 (6 d post change), 38 (10 d post change), and 42 (14 d post change). Fecal microbiota data were evaluated using QIIME2. All other data were analyzed using the Mixed Models procedure of SAS, with P < 0.05 being considered significant. B. subtilis supplementation of the kibble diet did not influence food or energy intake, fecal output, ATTD, most serum metabolites, hematology, fecal characteristics, fecal bacterial alpha and beta diversity indices, and dysbiosis index, demonstrating the safety of the strain in dogs. However, fecal Streptococcus and Blautia abundances were higher in High dogs than Low or Control dogs, while E. coli abundance was less in Low dogs than High and Control dogs. The abrupt change to a canned diet led to significant alterations in fecal characteristics, dysbiosis index, and bacterial abundances, which were not influenced by B. subtilis supplementation. Bacterial alpha diversity measures were affected, with observed ASV (amplicon sequence variants) and the Fisher Index reducing, and the Shannon Index increasing by dietary change. The abrupt dietary change caused a distinct shift in microbial communities, as evidenced by principal coordinates analysis plots. The relative abundances of various fecal bacterial taxa, including Bifidobacterium, Faecalibaculum, Turicibacter, and Lactobacillus were decreased, while Collinsella, Ruminococcus gnavus group, and Escherichia-Shigella were increased with the dietary change. Our data support the notion that daily supplementation of 1 – 5×109 CFU of B. subtilis ATCC PTA-122264 in healthy dogs is safe and does not affect markers of general health and fecal characteristics, warranting further exploration.

Comparison of the Efficacy and Welfare of Different Training Methods in Stopping Chasing Behavior in Dogs.

Controversy surrounds the efficacy and welfare implications of different forms of dog training with several studies asserting that electronic shock collars have negative welfare impacts while not being more effective than non-aversive methods. However, these studies did not specify the schedule and intensity of punishment used or the effectiveness of the training method. In the current study, we attempted to train dogs across six sessions to desist from chasing a fast-moving lure in one of three randomly assigned conditions and then tested for retention and generalization in four further test trials. Group A was trained with e-collars; Group B was trained with non-aversive methods and the lure moving as with Group A; and Group C was trained as for Group B but with the lure initially moving slowly before its speed was progressively increased. All dogs in Group A stopped running towards the lure after one or two sessions, and none chased the lure in the first three tests: 67% of these dogs chased the lure in the final test in a novel arena. None of the dogs in the either Group B or C successfully refrained from chasing the moving lure in training or any test. Video behavior coding indicated few stress-related behaviors across the training groups.

First Sero-Molecular Diagnosis of Toxoplasma gondii and Toxocara spp. Infections in the Police Dogs and Their Trainers in Iran.

Toxoplasma gondii (T. gondii) and Toxocara spp. are two types of parasites that can infect humans and various animals, including dogs. Police dogs and their trainers have a vital role in law enforcement, and their health and well-being are crucial for them to effectively carry out their duties. No study has yet been conducted on the prevalence of T. gondii and Toxocara spp. infections among police dogs and their trainers in Iran. The objective of this study was to determine the sero-molecular prevalence of T. gondii and Toxocara spp. infections in police dogs and their trainers in Tehran, the capital of Iran. In Tehran province, the anti-narcotics police have nearly 200 well-trained police dogs. Each dog is assigned a dedicated trainer and upon completing missions, is housed separately in a designated area. In the present study, a total of 150 samples were gathered. These included 50 blood samples from randomly selected police dogs, 50 fecal samples from the same dogs, and 50 blood samples from their trainers. The Modified Agglutination Test (MAT) was performed to detect T. gondii antibodies in dog blood samples and the ELISA system was utilized to identify anti-Toxoplasma and anti-Toxocara antibodies in the sera of the dog trainers. A specific segment of the SAG2 and ITS genes were amplified via nested-PCR in order to molecularly detect T. gondii in human blood samples and Toxocara spp. in dog fecal samples. Regarding serological findings, the prevalence of T. gondii in dog and human blood samples was 4% (2/50) and 10% (5/50), respectively. According to reports, the seroprevalence of Toxocara spp. in human blood samples was 6% (3/50). No statistically significant association was found between the prevalence of the examined parasites and variables (age, sex, and breed) in dogs, as well as the age variable in military personnel. Molecular findings showed that out of the 50 dog fecal samples and 50 human blood samples, there was no presence of Toxocara spp. and T. gondii, respectively. Understanding the prevalence of parasitic infections helps public health officials assess the risk to human and animal populations. This information can guide the development of prevention and control measures to reduce the spread of these infections. Overall, the prevalence of parasitic infections, particularly T. gondii and Toxocara spp., in police dogs and their trainers remains uncertain and necessitates further in-depth research.

Molecular detection of Anaplasma phagocytophilum, Borrelia theileri and Severe fever with thrombocytopenia syndrome virus (SFTSV) in military working dogs and ticks collected from the Republic of Korea Army garrisons in Gangwon Province in 2021–2022

AbstractTick‐borne pathogens (TBPs) are an emerging concern to humans and animals in the Republic of Korea, especially within the military zones of Gangwon Province, a mountainous region abundant with wild fauna and ticks. This study aimed to detect six TBPs in military working dogs (MWDs) and ticks in this region using Nested polymerase chain reaction (nested PCR) and sequencing. The targeted pathogens included Anaplasma phagocytophilum, Bartonella henselae, Borrelia spp., Orientia tsutsugamushi, Severe fever with thrombocytopenia syndrome virus (SFTSV) and tick‐borne encephalitis virus (TBEV). A total of 164 serum samples from MWDs were collected at the Korean Army Military working dog training center and 1418 ticks were collected at various training sites between June 2021 and August 2022. Haemaphysalis longicornis was identified as the predominant species (98.3%, n = 1394), followed by Haemaphysalis flava (1.6%, n = 22) and Ixodes nipponensis (0.1%, n = 2). This study detected A. phagocytophilum and Borrelia theileri in 1.4% (1/72) of the tick pools and detected SFTSV in 0.6% (1/164) of MWD serum samples. The MWD found to be infected with SFTS was a German Shepherd, but showed no significant clinical signs, with a normal complete blood count (CBC). In the phylogenetic analysis, three sequences were acquired. One sequence (OR865211) exhibited 100% homology with 16S rRNA of A. phagocytophilum identified from animals and human patients in the Republic of Korea. Another sequence (OR865152) displayed 99.34%–100% sequence similarity with 16S rRNA of B. theileri fragments. The third sequence (OR865115), which belongs to the SFTS B‐1 genotype, showed 94.7% sequence similarity to a strain identified in the Republic of Korea (KY789441).

Understanding in the canine classroom: learning to ‘lean’

ABSTRACT Using an ethnomethodological approach, we examine a particular case of a dog and its handler learning the ‘lean’ command. In this scene of instruction, we come upon a place where the uses of a word are taught to both dog and human. Revisiting Vicki Hearne’s influential book on animal training, we reflect on animals in conversation with their trainers, and the interconnected problems of understanding and of a dog’s specific rights. We describe the establishing of a new command as a body position, location and duration. The opening and closing of a door, as part of learning the new command, poses a puzzle of both instruction and rights for the dog as pupil. Our findings begin to contribute to the ‘missing what’ of dog training and question the limits of animal geographies in relation to the ethics in, and of, training and education with animals. In addition, we show how animal geographers can learn from and describe the public availability of intersubjective practices. Specifically, we describe the witnessable organisation of learning new commands, as part of which, we acknowledge and are attentive to the dog’s work, thereby contributing to studies of animal training, cross-species communication and classrooms.

SimuVet: a preliminary study of the innovative development of a simulator for epidural anesthesia training in dogs.

Epidural anesthesia in dogs is a locoregional anesthesia technique used in veterinary medicine, becoming an important integrated application in the anesthetic protocol to provide safer and more effective analgesia to patients. For this, professionals must adhere to rigorous guidelines and possess technical skills. In this context, in veterinary education, the development of practical clinical skills represents a crucial aspect in the training of these professionals. However, traditional teaching methods have proven insufficient to ensure a consistent level of competence among recent graduates. The introduction of non-animal alternatives for educational purposes has contributed to the development of simulation-based teaching, an innovative and accessible field capable of enhancing pre-clinical proficiency in students and reducing the use of live animals and cadavers. Despite its application in various areas of veterinary education, there are no conclusive results regarding the development of accessible simulators capable of effectively enhancing training in epidural anesthesia in dogs. Therefore, this article represents a pioneering study aimed at sharing a method for creating SimuVet, a realistic simulator for training epidural anesthesia in dogs. The simulator was fully developed by veterinary researchers with limited experience in 3D printing and, after preliminary analysis, demonstrated excellent performance and ultrasonographic anatomy. Future work will focus on the formal validation of this simulator with the aim of improving the teaching and learning process for students and experts in performing epidural anesthesia in companion animals.

Canine olfactory detection and its relevance for the medical identification of patients with COVID-19

Introduction The assessment of Volatile Organic Compounds (VOCs) in exhaled breath or sweat represents a potential non-invasive and rapid diagnostic tool for respiratory diseases. Objective To determine if trained dogs can reliably identify the odour associated with COVID19. Methods This is a monocentric prospective study carried out in the Emergency Department (ED) of a university hospital fromJulyto November 2021.Axillary sweat samples from all patients were collected bytwo trained health care professionals. The samples were collected in the form of sterile gauze swabs placed under the armpits for at least 4 h for each patient.Then, Tubes wereshiftedto the double-blind dog training centre for VOC detection by two individuals. Results Dogs were tested using a total of 129 axillary sweat samples; 69 of the 107 patients who tested positive for COVID-19 based on their odours had a positive PCR/Antigen test and 19 of the 22 patients who were tested negative for COVID-19 by the dogs had a negative PCR test. The sniffer dog infection detection method had a sensitivity of 95.83% and a specificity of 33.33%. The PPV was 64.49% and the NPVwas 86.36%. The measurement of the intensity of the connection between the two variables (disease/sign) was very strong (Q = 0.84). This link is statistically significant (X2 = 19.13) with a probability p ≤ 0.001. Conclusion Overall, the use of trained detection dogs as a screening method for SARS-CoV-2 is an interesting avenue of research that warrants further exploration and validation.

The Two‐Inquiry Rule for Service Animals and Free Speech

The Department of Justice's regulations for the Americans with Disabilities Act allow two inquiries about whether a dog is a service animal. These regulations have been in place for almost 15 years but have generated little litigation over what is plainly a content‐based speech prohibition. Most recently, in Stalder v. Colorado Mesa University, a Colorado court of appeals held that a Colorado Mesa University staff member's “reasonable suspicion” that a student's dog was not a genuine service animal did not justify an inquiry into the student's medical records or the dog's training history before the staff member authorized access to a campus gym (https://bit.ly/3yLEJnC).

Боротьба з контрабандою: заходи та виклики

Ukraine, as a modern state, faces the challenge of effectively combating smuggling, which not only leads to significant budget losses but also poses a threat to national security and economic development. This article discusses the key aspects of this problem, from the causes of smuggling of equipment to the low level of incentives for customs officers and the threats they face. The reasons for smuggling are discussed, such as corruption, excessive customs duties and taxes, and imperfect legislation. The article also considers the need for parliamentary and public control over the actions of customs and border authorities, as well as optimization of taxation to ensure effective protection of the domestic market. Particular emphasis is placed on the importance of international cooperation, technical support, dog training and public education for the successful fight against smuggling. The article also discusses the problem of low salaries and poor incentives for customs officers, which can jeopardize the effectiveness of the fight against smuggling. The article concludes with a section on possible threats to customs officials and ways to address them, including the possibility of threats, bribery and other negative influences that complicate their work. This article also discusses comprehensive measures such as technical support for customs, the development of a dog service, and the importance of public education for the successful fight against smuggling. The low level of salaries among customs officers and their weak incentives to disclose smuggling schemes are seen as a systemic problem that requires a comprehensive approach and solution. The author analyzes the threats that may be directed at customs officials by smugglers and criminal elements. Scenarios of influence, possible bribery, threats and other negative interactions are discussed in order to ensure effective measures to protect customs and border services. All these aspects interact and influence the success of the fight against smuggling in Ukraine. The article highlights the need for a systematic approach and cooperation of all stakeholders – government agencies, the public and international partners – to create an effective system that minimizes the risks and losses from smuggling.

Using ethically sourced training aids for human remains detection dog training

Human remains detection dogs (HRDDs) play vital roles in forensic investigations and search and rescue missions by detecting decomposing human remains. However, there is a lack of standardized training protocols globally. This study evaluates various ethically sourced HRDD training aids, including amputated limbs, blood, and teeth used by the Ontario Provincial Police (OPP). Expanding on prior research, this study assesses amputated limbs stored outdoors, bone, tissue, blood, and teeth. The volatile organic compound (VOC) profiles of these aids are compared to cadavers decomposing at the Research in Experimental and Social Thanatology (REST) facility. The results highlighted that the combined VOC profile from all HRDD training aid types demonstrates a 68% similarity to REST cadavers, emphasizing the potential benefit of exposing HRDDs to a diverse range of training aids. This is because the similarities in VOC profiles of individual training aid types (amputated limbs stored indoors, bone, blood, tissue, amputated limbs stored outdoors, teeth) with REST cadavers were lower than 68%. Teeth (without organic matter) were identified as the least ideal training aid for enabling dogs to detect cadavers based on VOC profiles and HRDD responses. However, training on teeth may be required for operational needs, particularly when HRDDs need to locate teeth during field searches. This study also highlights the effectiveness of using amputated limbs and blood together as they comprise a majority of the 68% VOCs found similar to the REST cadavers and elicit desirable HRDD responses to decomposition odor.

Participation in a Prison-Based Training Programme Is Beneficial for Rescue Dogs.

Dogs are often relinquished because of behavioural issues which may be exacerbated in rehoming centres. Prison-based dog training programmes (DTPs) may enhance outcomes for rescue dogs by providing socialisation and training opportunities to improve behaviour, welfare and likelihood of rehoming. We assessed whether dogs benefitted from participation, 1-3 times per week, in a prison-based DTP in which male young offenders learn how to train and care for dogs waiting to be rehomed. Within DTP sessions, there was significant improvement on a range of training tasks (n = 42 dogs). Analyses of videos (n = 17 dogs) in the kennels and a training barn pre- and post-DTP participation showed improvement in some positive behaviours, but no significant change in other behaviours. Subjective ratings by staff of the dogs' behaviour were made (n = 20 dogs). Desirable behaviours (e.g., playful/friendly) increased, and most undesirable behaviours (e.g., frustrated and noisy) decreased. Participation in the DTP did not mitigate all negative behaviours. However, improvements are consistent with enhanced welfare and likelihood of successful rehoming. Prison-based DTPs can be effective in supporting the work of animal rescue organisations to improve outcomes for dogs, while offering people in custody an opportunity to engage in purposeful activity and provide a community service.

De-centring the human: Multi-species research as embodied practice

This article focuses on embodiment and the centrality of embodied methods to multi-species research. We argue that taking the body as our methodological starting point is essential to researching human–animal relations but that bodies engage with and are engaged by the research process in a multiplicity of ways. In this we follow Vinciane Despret’s analysis of the partial affinities between animal scientists’ bodies and the animals they are researching and suggest that sociology’s distinction between sociology of and sociology with the body glosses over the complexities of inter-corporeal encounters. We explore these questions through a discussion of our multi-species ethnography of dog training cultures in the UK, looking at the training of companion dogs, guide dogs and police dogs. We pay attention to the different forms of embodied engagement that these training cultures make possible for us as researchers and reflect on the place of embodied communication in both the training and research relationship. We consider the disembodied training necessitated by the transition to online classes during the Covid pandemic and the consequences of this for our ability to create partial affinities with the dogs and their humans. We argue that the methodological challenges of our times require that we develop methods that attend to our multi-species world, rather than focusing exclusively on the human, and that bring into being a social reality which is less anthropocentric.

Training Methods Used by Dog Guardians in the United States: Prevalence, Sources of Information, and Reasons for Use.

While there has been recent attention in the scientific community on the ethical and welfare implications of different dog training methods, less research has investigated what methods and training tools United States dog guardians use, where they obtain information about dog training, and the reasons they give for their choices of method. We conducted two surveys with nearly 800 Arizona State University undergraduate students to gain a more realistic look into how dog guardians in the United States train their dogs and where they are receiving their training information. Only 5% of respondents reported utilizing a trainer when they had concerns regarding their dog's behavior; 60% would ask a friend or family member or seek advice online. Few reported taking their dog to any training classes; 70% reported either training the dog themselves or not implementing any formal training. When asked general questions, most respondents reported using rewards-based methods but, when asked about specific problem behaviors, 57% of respondents noted that they would use auditory or physical corrections. Respondents who trained with rewards-based methods reported that these methods of training were more effective significantly more frequently than those who trained with mixed methods reported that those methods were most effective (Fisher's Exact Test, p < 0.01).

Automatic classification of dog barking using deep learning

Barking and other dog vocalizations have acoustic properties related to emotions, physiological reactions, attitudes, or some particular internal states. In the field of intelligent audio analysis, researchers use methods based on signal processing and machine learning to analyze the digitized acoustic signals’ properties and obtain relevant information. The present work describes a method to classify the identity, breed, age, sex, and context associated with each bark. This information can support the decisions of people who regularly interact with animals, such as dog trainers, veterinarians, rescuers, police, people with visual impairment. Our approach uses deep neural networks to generate trained models for each classification task. We worked with 19,643 barks recorded from 113 dogs of different breeds, ages and sexes. Our methodology consists of three stages. First, the pre-processing stage prepares the data and transforms it into the appropriate format for each classification model. Second, the characterization stage evaluates different representation models to identify the most suitable for each task. Third, the classification stage trains each classification model and selects the best hyperparameters. After tuning and training each model, we evaluated its performance. We analyzed the most relevant features extracted from the audio and the most appropriate deep neural network architecture for that feature type. Even if the application of our method is not ready for being used in ethological practice, our evaluation showed an outstanding performance of the proposed method, surpassing previous research results on this topic, providing the basis for further technological development.

In Case You Haven't Heard…

Can dogs be depressed? According to Veterinarians.org, researchers in the 1980s found that canines can go through behavioral changes for various reasons, prompting them to experience extreme emotions, just like their human counterparts, People recently reported. Information shared on Veterinarians.org noted that some of the main signs of depression in dogs include “reduced activity levels and a desire to play,” plus “clinginess or social withdrawal” and “a loss or change in appetite.” “Excessive licking that brings comfort” and “uncharacteristic whining or howling” are other signs of canine depression, according to the organization. A big cause of depression in dogs, the organization noted, can be from experiencing a loss, which can range from that of a human companion or another pet living in the same home. Dogs can also be affected by environmental changes, such as the addition of a new pet or baby, or from something such as a change in scenery from moving, per Veterinarians.org. Dog trainers can help protect against depression in dogs by helping rid a pet of “established and unwanted behaviors through conditioning or positive reinforcement.” Veterinarians will sometimes medicate dogs with prescription drugs, similar to ones that humans take for depression, including Zoloft and Xanax. When prescribed, these medications may take up to four to six weeks to kick in and show effective changes, according to Veterinarians.org.
