The genetic lineage of rabies virus (RABV) associated with dogs has not been found in the state of São Paulo since 1998, and all cases of rabies in domestic animals reported since then have involved the RABV lineage that circulates in bats. As there has been a change in the rabies transmission cycle in cats and dogs, we decided to analyze the tests used to diagnose rabies in these animals in the 15-year period from 2002 to 2016 in the state of São Paulo. During this period, 85,508 central nervous system (CNS) samples from dogs and cats were submitted to the Rabies Diagnosis Section at the Pasteur Institute of São Paulo for testing...

Castration of dogs is a widespread practise with clear justification in population control and knock-on benefits for animal welfare. Deleterious behavioural consequences of castration are believed to be negligible. Gonadectomy is widely recommended as part of a multi-factorial approach to prevent problems including aggression in dogs. However, the consequences of early castration on health are still being debated. The current study focused on the reported behaviour of 6,235 male dogs castrated before 520 weeks of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ)...

Certain personality traits (e.g. anxiousness, fearfulness), are known to affect the cognitive processing of environmental stimuli, such as the judgement of ambiguous stimuli (judgement bias). Our aim was to assess if personality traits are predictive of a more or less 'pessimistic' or 'optimistic' judgement bias in the domestic dog. We assessed dog personality (N = 31) using two validated protocols: the Dog Mentality Assessment (standardised battery test) and the CBARQ (owner-based survey). We used a common task based on the animals' latency to approach a bowl placed in one of three ambiguous positions (Near Positive, Middle, Near Negative) between a baited (Positive) and a non-baited food bowl (Negative) to assess judgement bias...

OBJECTIVE: To report a case of severe lactic acidosis and hypoglycemia due to acute metformin intoxication in a dog. CASE SUMMARY: A female neutered Rat Terrier was presented for an acute onset of seizure-like episodes, weakness, and vomiting approximately 14 hours after ingestion of 198 mg/kg of metformin. The dog was found to be laterally recumbent, paddling, and unresponsive shortly before presentation. On physical exam, the dog was in hypovolemic shock and hypothermic...

Secretory carcinoma of the salivary glands, also known as mammary analogue secretory carcinoma, is a recently described tumor characterized by generally indolent clinical behavior and recurrent ETV6-NTRK3 fusions. However, a small subset of recent cases with high-grade histology, aggressive behavior, or alternate molecular findings are expanding the spectrum of this entity. In this case, a 59-year-old female presented with an infiltrative submandibular gland tumor that was originally classified as a high-grade acinic cell carcinoma, papillary-cystic variant...

Macrophages represent a major component of the overall leucocyte population within neoplasms and are important for tumour behaviour in several cancers in human beings. However, little information regarding their role in canine mammary tumours (CMTs) is available. The aim of this study was to address the potential role of tumour-associated macrophages (TAMs) in CMTs. TAMs in CMTs excised from 82 female dogs were quantified at high power (400× magnification) and categorised as low (≤50) or high (>50) TAM counts...

While dog owners ascribe different emotions to their pets, including jealousy, research on secondary emotions in nonhuman animals is very limited and, so far, only one study has investigated jealousy in dogs (Canis familiaris). This work explores jealousy in dogs one step further. We conducted two studies adapting a procedure devised to assess jealousy in human infants. In each study 36 adult dogs were exposed to a situation in which their owner and a stranger ignored them while directing positive attention towards three different objects: a book, a puppet and a fake dog (Study 1: furry; Study 2: plastic)...

Enhancer of zeste homolog 2 (EZH2) shows upregulated expression in tumors and is an important driver of tumor development and progression. However, the mechanism underlying the mediation of tumor aggressiveness by EZH2 remains unclear. We here investigated the levels of EZH2 in various normal and tumorous dog tissues and compared these patterns with those of the corresponding human tissues. Immunohistochemical analysis showed positive staining for EZH2 in 76 of 82 cases of canine tumors, whereas low or negligible staining occurred in normal tissues and other canine tumors, including hepatocellular adenoma and lipoma...

Plasmacytoid and rhabdoid variants of urothelial carcinomas (UCs) of the urinary bladder have been described in humans with plasma cell-like or rhabdoid cellular appearance and aggressive clinical outcome. Canine UC of the bladder is generally classified as papillary/nonpapillary and infiltrating/noninfiltrating with limited information regarding other histological patterns. We report 3 cases of UC of the urinary bladder showing a unique discohesive cellular morphology with malignant behavior resembling the human plasmacytoid and rhabdoid variants of UC, which may raise some difficulties in diagnosis...

Purulent pericarditis is a rare entity, defined as the presence of neutrophilic pericardial effusion which is infected by a bacterial, fungus or parasite agent. The diagnosis can be challenging, especially if patients have taken previous antibiotic therapy; on the other hand the recognition of this pathology is often made late, with the onset of severe symptoms or signs of cardiac tamponade or even only at the autopsy. The authors describe the case of a 82-year-old woman with history of extensive laceration of the right lower limb from a dog bite in July 2016, admitted to the Cardiology Department one month later for Acute Pericarditis...

BACKGROUND: Nowadays obesity is a common problem as it leads to abdominal deformation and people's dissatisfaction of their own body. This study has explored using a new surgical technique based on a different incision to reform the flank skin laxity and dog ear plus aggressive liposuction on women with abdominal deformities. METHODS: From May 2014 to February 2016 , 25 women were chosen for this study. All women had a body mass index more than 28 kg/m2 , flank folding, bulging and excess fat, abdominal and flank skin sagging and laxity...

A 9-year-old golden retriever dog was diagnosed with a left retrobulbar mass. Fine-needle aspirations and incisional biopsies resulted in discordant diagnoses: myxosarcoma/myxoma or rhadomyosarcoma, respectively. Immunohistochemistry following exenteration allowed definitive diagnosis of malignant peripheral nerve sheath tumor with fibromyxomatous differentiation. Fifteen weeks after surgery, an aggressive recurrence resulted in euthanasia.

Mental and physical benefits of dogs have been reported for adults and children with special needs, but less is known about benefits of cats for children. A cat that can be held by a child could provide important therapeutic companionship for children with severe or less severe autism spectrum disorder (ASD) who otherwise may lack prosocial behaviors. Because relatively little is known about the behavior of cats around children, we conducted this study. Phase 1 gathered web-survey data from families having an adult cat and a child with ASD ( n  = 64)...

The goal of this prospective pilot study was to use naturally occurring canine mast cell tumors of various grades and stages as a model for attempting to determine how glucose uptake and markers of biologic behavior are correlated. It was hypothesized that enhanced glucose uptake, as measured by 2-[fluorine-18]fluoro-d-glucose-positron emission tomography/computed tomography (F18 FDG PET-CT), would correlate with histologic grade. Dogs were recruited for this study from a population referred for treatment of cytologically or histologically confirmed mast cell tumors...

This study examines the activity budgets and social behaviours initiated and received by 69 focal dogs in an off-leash dog park for 400 s after entry, a time of high activity about which little is known. Using motivationally-neutral labels for social behaviour categories, we describe the frequency of behaviours, and correlations among them. We then examine these relationships in the context of proposed functions for some behaviours in dogs, in terms of information gathering and communication, including visual and tactile signalling...

Gonadectomy is widely used to treat and prevent behavior problems including the aggressive behavior of dogs. The aim of this study was to determine whether aggressive behavior toward familiar people, strangers, or other dogs was significantly different in dogs gonadectomized at various ages vs. intact dogs using the Canine Behavioral Assessment Research Questionnaire (C-BARQ) with multivariate analysis. Of 15,370 initial surveys, those for dogs reported to have been gonadectomized at less than 6 weeks of age or to correct a behavior problem, and those with incomplete answers to questions regarding independent or dependent variables were excluded, leaving 13,795 for the analysis of aggressive behavior toward familiar people: 13,498 for aggressive behavior toward strangers and 13,237 for aggressive behavior toward dogs...

Trait impulsivity is an increasingly relevant topic for human and non-human animal personality research. There are similarities in dog and human manifestations of trait impulsivity at the behavioural, genetic, and neurobiological level. We investigated a well-validated measure of dog impulsivity and responsivity (the Dog Impulsivity Assessment Scale, DIAS) and a neuropsychological theory of human trait approach and avoidance (the Reinforcement Sensitivity Theory of personality, RST). Owners reported their dogs' dispositional behaviour on the DIAS, an RST scale modified to describe dogs' behaviour, and a list of common dog behaviour problems...

Death-associated protein kinase (DAPK) is a serine/threonine kinase and a tumour suppressor gene. Diffuse large B-cell lymphomas with inactivated DAPK through hypermethylation of a CpG island is known to result in a biologically aggressive phenotype in humans. This retrospective study was carried out to analyse the prognostic significance of DAPK CpG island hypermethylation in canine lymphoma. We hypothesized that DAPK CpG island hypermethylation can be a negative prognostic indicator in dogs with nodal high-grade B-cell lymphoma...

BACKGROUND: Dog bites are common in developing countries including Ghana, with the victims often being children. Although some breeds of dogs have been identified as being more aggressive than others, all dog bites carry a risk of infection. Immediate and initial assessment of the risk for tetanus and rabies infection with appropriate interventions such as wound management and subsequent selection of prophylactic antibiotics are essential in the management of dog bites. This study examined the management of patients with dog bites by frontline service providers at primary healthcare facilities in the Greater Accra Region, Ghana...
