An unusual relationship between the axillary artery and brachial plexus in a cross-breed dog cadaver: a proposal for revising the terminology for nerve loops

In the left axilla of a formalin-embalmed adult female cross-breed dog, an unusual course of the axillary artery in relation to the brachial plexus was noted. A part of the axillary artery after the origin of the subscapular artery coursed through the loop formed by the contributions of the caudal pectoral and lateral thoracic nerves and then between the median and ulnar nerves. Thus, the common trunk for the latter two nerves was missing. Instead, in the proximal brachium, they communicated with each other in both directions. A communicating branch between the cranial and caudal pectoral nerves forming a nerve loop, ansa pectoralis lacked the axillary artery and was instead traversed by the subscapular artery. This is a variation in the relationship between the axillary artery and brachial plexus in the domestic dog and has not been reported in the literature yet. The axillary artery entrapped by the contributions of the caudal and lateral thoracic nerves may be considered as a risk factor for the neuroarterial compressions with non-specific signs and should be taken into account both in surgery and imaging.

Comparison of Shelf-stable and Conventional Resuscitation Products in a Canine Model of Hemorrhagic Shock.

Treatment of severe hemorrhagic shock typically involves hemostatic resuscitation with blood products. However, logistical constraints often hamper the wide distribution of commonly used blood products like whole blood. Shelf-stable blood products and blood substitutes are poised to be able to effectively resuscitate individuals in hemorrhagic shock when more conventional blood products are not readily available. Purpose-bred adult dogs (n = 6) were anesthetized, instrumented, and subjected to hemorrhagic shock (MAP <50 mmHg or 40% blood volume loss). Then each dog was resuscitated with one of five resuscitation products: (1) lactated ringers solution and hetastarch (LRS/heta), (2) canine chilled whole blood (CWB), (3) fresh frozen plasma (FFP) and packed red blood cells (pRBC), (4) canine freeze-dried plasma (FDP) and hemoglobin-based oxygen carrier (HBOC), or (5) HBOC/FDP and canine lyophilized platelets (LyoPLT). Each dog was allowed to recover after the hemorrhage resuscitation event and was then subjected to another hemorrhage event and resuscitated with a different product until each dog was resuscitated with each product. At the time when animals were determined to be out of shock as defined by a shock index <1, MAP (mm Hg) values (mean ± standard error) were higher for FFP/pRBC (n = 5, 83.7 ± 4.5) and FDP/HBOC+LyoPLT (n = 4, 87.8. ± 2.1) as compared to WB (n = 4, 66.0 ± 13.1). A transient increase in creatinine was seen in dogs resuscitated with HBOC and FDP. Albumin and base excess increased in dogs resuscitated with HBOC and FDP products compared to LRS/heta and CWB (p < 0.01). Combinations of shelf-stable blood products compared favorably to canine CWB for resolution of shock. Further research is needed to ascertain the reliability and efficacy of these shelf-stable combinations of products in other models of hemorrhage that include a component of tissue damage as well as naturally occurring trauma. This is a Therapeutic/Care management study with Level of Evidence IV.

Assessment of testicular stiffness in fertile dogs with shear wave elastography techniques: a pilot study.

Ultrasound of the testes is important in the evaluation of breeding dogs, and recently advanced techniques such as Shear Wave Elastography (SWE) have been developed. This study focused on evaluation of normal testicular stiffness in healthy and fertile male dogs, employing both qualitative (2D-SWE) and quantitative (pSWE, 2D-SWE) techniques. Nineteen dogs of various medium-large breeds aged 3.39 ± 2.15 years, and with a history of successful reproduction were included after clinical, B-mode and Doppler ultrasound of testes and prostate, and semen macro and microscopic evaluations. pSWE involved square regions of interest (ROIs) placed at six different points in the testicular parenchyma, while 2D-SWE depicted stiffness with a color scale ranging from blue (soft) to red (stiff), allowing a subsequent quantification of stiffness by the application of 4 round ROIs. The results showed a mean Shear Wave Speed (SWS) of 2.15 ± 0.39 m/s using pSWE, with lower values above the mediastinum compared to below, and in the center of the testis compared to the cranial and caudal poles. 2D-SWE demonstrated a uniform blue pattern in the parenchyma, and a mean SWS of 1.65 ± 0.15 m/s. No significant differences were found between left and right testes, above and below the mediastinum, or among breeds. No correlations were observed between mean SWS and body condition score, age, testicular and prostatic volume. Weight was positively correlated with mean SWS only by 2D-SWE. By performing semen analysis and enrolling only healthy and fertile adult dogs, we ensured both structural and functional integrity of the testes. This pilot study represents a valuable baseline data for testicular stiffness by both pSWE and 2D-SWE with a Mindray US machine in medium-large sized healthy and fertile dogs, pointing out the potential role of SWE in the non-invasive fertility assessment and management of breeding dogs.

Effect of dental chew on reducing dental plaque, dental calculus and halitosis in beagle dogs

Periodontosis is the most common clinical disease in adult dogs, which is mainly caused by plaque accumulation and seriously endangers the oral health of dogs and even cause kidney, myocardial, and liver problems in severe cases. The aim of this study was to determine the clinical efficacy of dental chew (Cature Brushing Treats product) with mechanical and chemical properties in beagles. The dogs in the experimental group were fed with a dental chew twice a day after meals; The control group had no treatment. Dental plaque was evaluated on the 14th day and 29th day, respectively. The concentration of volatile sulfur compounds (VSC) in the breath and dental calculus were also evaluated on the 29th day. The results showed that there was no significant difference in the indexes of dental plaque on the 14th day. While they had significantly reduced accumulation of plaque (37.63%), calculus (37.61%), and VSC concentration (81.08%) compared to when receiving no chew on the 29th day.

Comparison of activity trackers in estimating canine behaviors

Classifying behavior by tracking acceleration has received increased interest lately. Here, we evaluated the performance of three commercial activity trackers in differentiating seven dog behaviors. Adult companion dogs (N = 70) performed still (lying, sitting, standing) and dynamic (walking, sniffing, trotting, playing) tasks, while wearing ActiGraph GT9X Link, Kaunila and FitBark devices placed on the neck collar and ActiGraph GT9X Link placed on the back. Each task was performed for 3 min within a session and repeated in two sessions; the behaviors were confirmed from video recordings. Activity scores of devices were calculated as median values for behavioral differentiation, and as minute-based values for inter-device correlations and cutoff analysis. Measurements of all devices correlated with each other, and median activity scores of all devices − unaffected by dog age, weight or sex − differentiated the still from dynamic behaviors. Dynamic behaviors were also differentiated from each other, with exception of walking vs. sniffing by back-placed ActiGraph GT9X and Kaunila. The definition of cutoffs between behaviors varied from moderate to high accuracy; defined cutoffs for standing and walking were the least accurate. The classification performance of the cutoffs had an accuracy of 80% in all the devices; thus, they performed reasonably well in classifying these behaviors.

Protein hydrolysate and oil from fish waste reveal potential as dog food ingredients.

The increased fish consumption by the growing human population in the world translates into an increase in fish waste. The reintroduction of these fish by-products into food and feed chains presents economic benefits and contributes to counteracting their negative environmental impact. Under this context, the present study aimed to evaluate the effects of the dietary inclusion of fish hydrolysate and oil obtained from fish waste (experimental diet) in substitution of shrimp hydrolysate and salmon oil (control diet) mainly imported from third countries on palatability, apparent total tract digestibility, fecal characteristics and metabolites, blood fatty acid profile, flatulence, and coat quality of adult dogs. A two-bowl test was performed to evaluate palatability by the pairwise comparison between the two diets. A feeding trial was conducted according to a crossover design with two diets (control and experimental diets), six adult Beagle dogs per diet, and two periods of 6 weeks each. The replacement of shrimp hydrolysate and salmon oil with fish hydrolysate and oil did not affect the first diet approach and taste, as well as the intake ratio. Generally, the digestibility of dry matter, nutrients, and energy was not affected by diet, but the intake of digestible crude protein (CP) and ether extract was higher, respectively, with the control and the experimental diet. The higher intake of eicosapentaenoic acid and docosahexaenoic acid with the experimental diet was reflected in a higher content of these long-chain polyunsaturated fatty acids and the omega-3 index of red blood cells, but it did not affect coat quality. The significantly higher intake of digestible CP with the control diet might have contributed to the higher fecal ammonia-N and valerate concentrations. Daily fecal output and characteristics were similar between diets. Overall, results suggest that fish hydrolysate and oil from the agrifood industry might constitute sustainable functional ingredients for dog feeding while adding value for wild fisheries, aquaculture, and fish farming under a circular economy approach and reducing dependence on imports from third countries with a high carbon footprint.

Domestic dogs maintain clinical, nutritional, and hematological health outcomes when fed a commercial plant-based diet for a year.

Domestic dogs can maintain health on complete and well-balanced canine plant-based nutrition (K9PBN). Novel insight on health outcomes in dogs consuming K9PBN is of relevance to veterinary professionals and consumers given a growing interest in non-traditional dog foods with perceived health benefits, while considering potential safety concerns. We aimed to investigate nutritional equivalence by measuring clinical health outcomes in adult dogs fed K9PBN over twelve months compared to a meat-based diet at baseline. We enrolled fifteen clinically healthy adult dogs living in households in Los Angeles County, California in a prospective cohort study and evaluated clinical, hematological, and nutritional parameters in dogs at 0, 6, and 12 months, including complete blood count (CBC), blood chemistry, cardiac biomarkers, plasma amino acids, and serum vitamin concentrations. The study found that clinically healthy, client-owned, adult dogs maintain health, based on physical exams, complete blood count, serum chemistry, plasma amino acids, serum vitamins, and cardiac biomarkers combined with client-reported observations, when fed commercial K9PBN over a twelve-month period. This study is the most comprehensive and longest known K9PBN investigation to date and provides clinically relevant evidence-based nutrition data and new knowledge on outcomes in clinically healthy dogs who thrive without consumption of animal-derived ingredients. These results also provide a valuable foundation for the future study of K9PBN as a potential nutritional intervention for clinically relevant pathologies in canine medicine. Lastly, it is of major relevance to One Health paradigms since ingredients produced independent of industrial food animal production are both more sustainable and help to circumvent ethical dilemmas for maintenance of health in domestic dogs.

Supplementation of tropical red seaweeds improved gut health indices, antioxidant status and immunity in adult dogs

Supplementation of tropical red seaweeds improved gut health indices, antioxidant status and immunity in adult dogs

The Canine Gut Health: The Impact of a New Feed Supplement on Microbiota Composition.

This study aimed to determine the impact of a novel formulation of a supplement composed of the natural ingredients, bromelain, quercetin, and Lentinula edodes, on the gut microbiota of healthy adult dogs. Adult healthy female dogs were administered either a placebo (CTR, n = 15) or the supplement (TRT, n = 15) over 28 days. Stool samples were collected for 16S rRNA sequencing before supplement administration (T0), at completion of supplement administration (T28), and one week after the end of supplement administration (T35) to characterize changes in the gut microbial communities. QIIME was used to determine both alpha- and beta-diversity, and ANCOM-BC was used to identify differences in taxonomic abundances before and after supplementation. We found a significant decrease in overall diversity in the CTR group but no significant differences in overall diversity in the TRT group over time. Furthermore, we found differences in the abundance of several taxa in both the CTR and TRT groups, but differences in the abundance of beneficial bacteria were more pronounced in the TRT group. Specifically, we found increases in the abundance of sequences belonging to the genera Bifidobacterium, Lactobacillus, and Pediococcus at T28 in the TRT group with significant increases in Bifidobacterium and Lactobacillus persisting at T35 when compared to T0. Importantly, members of these genera are considered important for their anti-inflammatory properties, vital for fostering a balanced and robust gut microbiota in dogs. The results of our study show the potential of our supplement to selectively enhance specific beneficial bacterial taxa, offering a targeted approach to modulating the gut microbiome without causing disruptions to the overall equilibrium.

A randomized trial to compare smooth monofilament suture vs. barbed suture using the three-layer continuous closure technique in canine ovariohysterectomy in a high-quality high-volume spay/neuter clinic.

The primary objective of this study was to compare time efficiency and complication rates between smooth monofilament suture (SMS) and barbed suture (BS) using the three-layer continuous incisional closure pattern after ovariohysterectomy in a high-quality high-volume spay/neuter clinic. The study was designed as a randomized controlled trial enrolling 71 adult female dogs. Dogs were randomly assigned to SMS or BS treatments. The effect of closure with BS or SMS on closure time was tested through multilevel, multivariable linear regression in a generalized linear mixed model. Body condition score, weight, and pre-closure incision length were tested as covariates. Surgeon was included in the model as a random effect. Pre-closure incision length (p = 0.01) and method (p ≤ 0.0001) were associated with closure time. Adjusting for pre-closure incision length, the average time for closure with SMS was 6.5 min (range 3.70-10.31 min), and the average time for closure with BS was 4.91 min (range 3.05-8.05 min). Accounting for the closure method, the closure time increased by 39 s for each additional centimeter of incision length. BS was more efficient than SMS when performing the three-layer continuous suture pattern. No short-term telemedicine-assessed complications were noted with either treatment method. BS can improve efficiency in surgical closures, especially considering large volumes of animals, and appears to have a similar short-term, telemedicine-assessed complication rate when compared to SMS.

Evaluation of the toxicogenetic potential of visceral leishmaniasis in naturally infected dogs and salivary samples for definitive disease diagnosis

Visceral leishmaniasis is an infectious and zoonotic disease caused by the protozoan Leishmania infantum chagasi, transmitted through the bite of the sandfly Lutzomyia longipalpis, with dogs serving as the primary reservoir. Given the increasing spread of this disease in dogs and its epidemiological and public health significance, this study aimed to investigate whether salivary samples from naturally infected dogs could serve as a diagnostic tool, attempting to replace invasive conventional methods. Additionally, the study analyzed the potential toxicogenetic effects of the disease. Ten adult dogs, both males and females, intact and neutered, of mixed breed, from Rifaina (SP) and attended at the Veterinary Hospital of the University of Franca, were included. These dogs exhibited various clinical signs suggestive of visceral leishmaniasis, with five of them confirmed through serological and parasitological examinations. Salivary samples were collected using sterile swabs from the five seropositive dogs, placed on glass slides, and stained with hematoxylin-eosin for subsequent analysis of amastigote forms of the protozoan using bright-field microscopy; the results were descriptive. Furthermore, bone marrow samples from the sternum were collected from the five seropositive dogs and compared with those from the five seronegative dogs to investigate the toxicogenetic potential of the disease through the micronucleus test. To assess possible genotoxicity, each slide made from bone marrow was analyzed for 2000 immature erythrocytes (IE), totaling 4000 IE/animal, and those containing micronuclei (MN) were identified (IE-MN). Cytotoxicity was determined by analyzing 1000 erythrocytes/slide, totaling 2000 erythrocytes/dog, and subsequently calculating the ratio of IE/IE+NCE (normochromatic erythrocytes). Toxicogenetic results of seropositive dogs were compared with seronegative dogs and statistically verified by simple analysis of variance (ANOVA). The protozoan Leishmania was not detected in any of the salivary samples from seropositive dogs. The mean frequency of IE-MN in seropositive dogs was statistically higher compared to seronegative dogs (p&lt;0.0001), indicating the genotoxicity of the disease. In two of the five seropositive dogs, a decrease in erythrocyte production suggested cytotoxicity of the disease. Given the established methodology, it can be inferred that simple saliva analysis, without more specific assays, does not detect amastigote forms of the protozoan in dogs seropositive for visceral leishmaniasis and should not replace established diagnostic methods. Additionally, the micronucleus test suggested the genotoxicity and cytotoxicity of the disease.

Comparison of the Haematological Parameters of Indigenous and Exotic ‎Dogs in Maiduguri, Nigeria

Health status of dogs may be assessed with haematological parameters, but adaptation to environmental stress can lead to adjustment of these normal parameters. This study was designed to compare the haematological parameters of indigenous and exotic dogs in Maiduguri during the hot dry season. Forty apparently healthy indigenous (n = 20) and exotic(n = 20) dogs of both sexes and aged from 3-48 months were used. Blood sample (5 ml) was collected from the cephalic vein of each dog in EDTA bottles. Parameters were determined using microhaematocrit method for packed cell volume (PCV), haemocytometery for red blood cell (RBC) count and total white blood cell (TWBC) count, cyanmethemoglobin method for haemoglobin concentration (Hb), and examination of stained blood smear for relative differential white blood cell (WBC) count. Mean corpuscular volume (MCV) and haemoglobin concentration (MCHC), and absolute differential WBC counts were calculated. The TWBC and neutrophil counts were significantly (p &lt; 0.05) higher in indigenousthan exotic dogs. Exotic females had significantly (p &lt; 0.05) lower MCHC and neutrophil count than indigenous females and all males. Age significantly (p &lt; 0.05) affected MCV, but the highest value was recorded in young exotic dogs. Adult indigenous dogs had significantly (p &lt; 0.05) higher neutrophil count than young indigenous and all exotic dogs. Monocyte count was significantly (p &lt; 0.05) higher in young than adult exotic and all indigenous dogs. However, haematologicalvalueswere within standard reference intervals for dogs.

Characterization of oral microbiota in 6–8-month-old small breed dogs

BackgroundPeriodontitis is the most common oral disease in dogs, and its progression and severity are influenced by risk factors, such as age and body size. Recent studies have assessed the canine oral microbiota in relation to different stages of periodontitis and niches within the oral cavity. However, knowledge of the bacterial composition at different ages and body sizes, especially in puppies, is limited. This study aimed to characterize the oral microbiota in the healthy gingiva of small breed puppies using next-generation sequencing. Additionally, we assessed the impact of dental care practices and the presence of retained deciduous teeth on the oral microbiota.ResultsIn this study, plaque samples were collected from the gingival margin of 20 small breed puppies (age, 6.9 ± 0.6 months). The plaque samples were subjected to next-generation sequencing targeting the V3-V4 region of the 16 S rRNA. The microbiota of the plaque samples was composed mostly of gram-negative bacteria, primarily Proteobacteria (54.12%), Bacteroidetes (28.79%), and Fusobacteria (5.11%). Moraxella sp. COT-017, Capnocytophaga cynodegmi COT-254, and Bergeyella zoohelcum COT-186 were abundant in the oral cavity of the puppies. In contrast, Neisseria animaloris were not detected. The high abundance of Pasteurellaceae suggests that this genus is characteristic of the oral microbiota in puppies. Dental care practices and the presence of retained deciduous teeth showed no effects on the oral microbiota.ConclusionsIn this study, many bacterial species previously reported to be detected in the normal oral cavity of adult dogs were also detected in 6–8-month-old small breed dogs. On the other hand, some bacterial species were not detected at all, while others were detected in high abundance. These data indicate that the oral microbiota of 6–8-month-old small breed dogs is in the process of maturating in to the adult microbiota and may also have characteristics of the small dog oral microbiota.

Haofa dog – An indigenous canine germplasm from Manipur, India

A study on Haofa dog was carried out at its breeding tract in Ukhrul and Kamjong districts of Manipur to find out its origin, distribution and phenotypic characteristics. A total of 100 adult Haofa dogs (50 male and 50 female) were recorded for studying physical characters and body measurement. Further, 69 number of observation were also recorded for studying body weights of adult male and female. In addition, 100 Haofa owners were interviewed to study the reproductive characteristics, management practices followed and their utility, etc. The study revealed that Haofa were of medium size with a compact body, broad chest, straight top line and slightly tucked up abdomen. The coat colour is usually black with grey skin while some dogs have black coat colour with white markings in ventral parts and tips of legs. The head of a Haofa dog is medium in size with a slightly trapezoid shape, while the forehead is usually prominent with the straight nasal bridge. Eyes are oval shaped with golden colour. Ears are erect and usually cropped at an early age. The dogs have short coats and their tails are usually semi-curved and docked usually at a young age. The adult body weight and average litter size at birth ranges from 22-31 kg and 3-8, respectively. Haofa is morphologically different from the other exotic breeds, crossbreeds or local dogs found in the state. Hence, it deserves to be recognized as a distinct breed of dog.

Characterization of the plasma proteome from healthy adult dogs.

Bloodwork is a widely used diagnostic tool in veterinary medicine, as diagnosis and therapeutic interventions often rely on blood biomarkers. However, biomarkers available in veterinary medicine often lack sensitivity or specificity. Mass spectrometry-based proteomics technology has been extensively used in the analysis of biological fluids. It offers excellent potential for a more comprehensive characterization of the plasma proteome in veterinary medicine. In this study, we aimed to identify and quantify plasma proteins in a cohort of healthy dogs and compare two techniques for depleting high-abundance plasma proteins to enable the detection of lower-abundance proteins via label-free quantification liquid chromatography-mass spectrometry. We utilized surplus lithium-heparin plasma from 30 healthy dogs, subdivided into five groups of pooled plasma from 6 randomly selected individuals each. Firstly, we used a commercial kit to deplete high-abundance plasma proteins. Secondly, we employed an in-house method to remove albumin using Blue-Sepharose. Among all the samples, some of the most abundant proteins identified were apolipoprotein A and B, albumin, alpha-2-macroglobulin, fibrinogen beta chain, fibronectin, complement C3, serotransferrin, and coagulation factor V. However, neither of the depletion techniques achieved significant depletion of highly abundant proteins. Despite this limitation, we could detect and quantify many clinically relevant proteins. Determining the healthy canine proteome is a crucial first step in establishing a reference proteome for canine plasma. After enrichment, this reference proteome can later be utilized to identify protein markers associated with different diseases, thereby contributing to the diagnosis and prognosis of various pathologies.

Tick-borne pathogens Ehrlichia, Hepatozoon, and Babesia co-infection in owned dogs in Central Thailand.

Tick-borne pathogens are transmitted by a wide range of tick species and affect both human and animal health. Understanding the diversity of these pathogens and their co-infection rates in domesticated animals in urban areas is crucial for effective disease management and prevention. In this study, a total of 565 owned dogs in the central region of Thailand were investigated for the infection rate of three genera of Ehrlichia, Hepatozoon, and Babesia infection using multiplex PCR. The results revealed an overall infection rate of 19.1%, with Ehrlichia having the highest infection rate (12.2%), followed by Babesia (2.5%) and Hepatozoon (1.4%). The rate of co-infection was 3%, with mixed infections involving two or three genera. Male dogs exhibited a slightly higher infection rate compared to females, although not statistically significant. Young adult dogs (1-3 years) showed the highest infection rate of both single infections and co-infections. Monthly infection rate indicated variations throughout the year, with co-infection rate significantly associated with overall infection rate. Clinical manifestations in three genera of infected dogs included thrombocytopenia and eosinopenia. The results of this study are useful to design strategies for the management and prevention of tick-borne diseases in the study area.

Canine glioma in the first year of life: 5 cases.

Most canine gliomas occur in adult and aged dogs, and reports in puppies < 12-mo-old are exceedingly rare. Here we describe the occurrence of gliomas in 5 dogs ≤ 12-mo-old. The affected patients (4 males, 1 female) were 3-12-mo-old (x̄ = 6.6-mo-old). None of the dogs were brachycephalic. Clinical signs consisted of dullness (2 cases), seizures (2 cases), vestibular signs, and deafness (1 case each). All patients were euthanized. Grossly, neoplasms were pale-tan or red, soft masses in the telencephalon (4 cases) or gelatinous leptomeningeal thickening in the brain and spinal cord (1 case). Neoplasms were classified as astrocytomas (3 cases) and oligodendrogliomas (2 cases) based on histology or histology and IHC. Our findings confirm that, while exceptionally rare, canine gliomas occur in the first year of life, and are clinically, morphologically, and immunohistochemically similar to gliomas in adult and aged dogs.

Diagnosis, Hematologic Profile, and Treatment of Cystoisosporiasis in Domestic Dog

Cystoisosporiasis infection is caused by Cystoisospora spp. or Isospora spp. in dogs. Cystoisospora spp. are protozoa ordo Eucoccidiorida. Cystoisosporiasis is considered more risky in puppies. Clinical manifestations of cystoisosporiasis tend to be watery diarrhea to melena in puppies which can also be concurrent with vomiting, and tenesmus, whereas in adult dogs known as symptomatic. A female domestic dog, aged &gt;1 yo was kept indoors and had not been vaccinated or anthelmintic drugs. The dog has changed in the consistency of slightly soft feces with a frequency of defecation 1–2 times a day. Diagnose performed using microscopic fecal examination with the floating method found the presence of Cystoisospora spp. oocysts, followed by the calculation of oocysts per gram (OPG) using a two-chamber McMaster to determine the degree of Cystoisospora spp. infection. Blood examination showed leukocytosis, granulocytosis, and hypochromic anemia. The treatment was administered of 15 mg/kg BW sulfadiazine orally every 12 hours for 7 days, 14 mg/kg BW metronidazole every 12 hours for 7 days, and 300 mg Hemafort® every 24 hours for 7 days. After 7 days of treatment, we reported normal fecal consistency and negative parasitic manifestation. Prevention was done by paying attention to treatment, immediately identifying the presence of oocysts, educating owners to avoid animal distress, and maintaining a good hygiene environment.

Safety and efficacy of a feed additive consisting of lanthanum carbonate octahydrate for dogs (Porus GmbH).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lanthanum carbonate octahydrate as a zootechnical feed additive for dogs. The additive is already authorised for use in feed for cats. The FEEDAP Panel concluded that the additive lanthanum carbonate octahydrate is safe for adult dogs at the maximum recommended level of 7500 mg/kg complete feed. The additive is not irritant to skin or eyes, is not a skin sensitiser and exposure by inhalation is considered to be unlikely. The Panel also concluded that lanthanum carbonate octahydrate is efficacious in the reduction of phosphorus bioavailability in adult dogs at the minimum inclusion level of 1500 mg/kg complete feed.

Characterisation, Conservation and Sustainable Utilization of Kombai Dog Breed: A Unique Genetic Resource of India

Kombai is an ancient dog breed of Tamil Nadu, India. The Kombai dog is renowned for its fierce loyalty to its family and aggressiveness towards its adversaries. They are incredibly powerful, extremely intelligent, courageous, protective, resilient, territorial, and amiable breed making them as excellent guard dogs. Other names of this breed are Indian/Tamil Bear Hound, Poligar Dog, Mandai War Dog and Indian Rottweiler. The significant feature of this breed is that it lacks a fierce bark, it barks infrequently. Kombai is a sight hound, it hunt by sight and speed rather than by scent and stamina. The breed originated from the foothills of the Western Ghats in Theni district, Tamil Nadu. The breeding tract of this dog are Kombai, Uthamapalaiyam, Pannaipuram, Thevaram, Periakulam, Bodinayakkanur, Cumbam and Kudalur of Theni district and consequently dispersed throughout the southern India. The variants of this breed are Pulicharai Kombai and Porr Kombai. Kombai is medium-sized dog with muscular physique. True to this type of breeds are tan, brown, or reddish brown in color with a black muzzle, hence it is called as “Karuvaisevalai” or “Karumunji naai”. Piebald and brindle coat types are less popular. The head of a Kombai dog appear to be slightly larger than the body as a whole. Large oval-shaped dark brown eyes, strong jaws, and a broad, deep chest characterize the Kombai, and it has single, uniform, dense coat that is neither patchy nor uneven. It has lean muscles and a ridge that runs the length of their spine in the opposite way strengthens the entire body. Their mid-length ears are mostly flat or fold over at the front or sometime erect. The legs are designed for agility and quickness. The tail has smooth hair and is long, curling at the edge like a sickle. An adult dog weigh up to 30kg (Male 25–32 kg; Female 20–25 kg) and 24 inches in height (Males: 22 to 24 inches; Females:19 to 22 inches). Average life span of this breed is 12-15years. Litter size is 4 to 6. Kombai dogs attain sexual maturity between 6-10 months. At present, the Kombai breed is becoming scarce and is in danger of going extinct as a result of ban on hunting, indiscriminate breeding, lack of knowledge about their significance, and shortage of traditional breeders. It is imperative to take immediate action to conserve this superior distinctive genetic resource. Establishment of Kombai breeders association and proper coordination and integration among various agencies is highly needed. This unique Kombai dog should be conserved in their innate habitats by implementing partaking approach by including breeders, communities, and other pertinent shareholders in conservation programs and it should be registered as breed.
