Gastric dilatation-volvulus (GDV) syndrome is a life-threatening emergency and its physiopathology and treatment have been studied for decades. Despite ongoing research, the mortality rate is still high. The aims of this study are to describe the treatment and outcome of GDV patients treated from 2011 to 2024 at the veterinary teaching hospital of Grugliasco (Turin, Italy); to analyze risk and prognostic factors, comparing the obtained data with current literature; and to evaluate how patients’ management has changed over the years. The study included 130 dogs with a confirmed GDV diagnosis that underwent surgery. The data were extracted from the digital and hardcopy clinical record, combined with the imaging diagnostic software and an interview submitted to the dogs’ owners. The analysis showed the predominance (25.38%) of German Shepherd dogs, as well as of males (59.25%); among the latter, intact dogs were most represented (53.1%). Age between 5–10 years was most frequent in the examined population (54.69%). The surgical technique went through changes during the examined period: the belt loop has been abandoned in favor of the incisional gastropexy. The survival rate of GDV surgically treated dogs was 86.4%. Lactate blood concentration and splenectomy were not assessed as relevant prognostic factors. Full article

Early socialization and appropriate adoption time are key factors in shaping canine behavior and welfare. Stress and behavioral challenges are major concerns for owners, often leading to abandonment. Stress can be assessed through physiological and behavioral indicators, with behavior being a noninvasive and practical measure. Canine development includes critical sensitive periods, particularly the socialization phase (3–12 weeks), when puppies form primary social bonds and adapt to novel stimuli. Lack of positive experiences during this period can lead to adult behavioral problems like fear, aggression, or anxiety. This study analyzed the behaviors of 107 dogs adopted at different ages (≤1 month to ≥4 months) and from varied origin contexts (shelters, breeders, private). Using the validated C-BARQ tool, the research found that the age at adoption significantly influenced behavior, with puppies adopted ≤1 or ≤2 months showing higher behavioral signs of fear, anxiety, and attachment and attention-seeking tendencies compared to those adopted later. The findings highlight the importance of socialization and appropriate adoption timing to prevent behavioral issues. The study underscores the value of educating owners and shelters about expected behavioral changes and the benefits of professional behavioral assessments. By fostering realistic expectations and proactive interventions, these insights aim to improve canine welfare and reduce abandonment rates. Full article

Cranial cruciate ligament rupture is one of the most prevalent orthopedic injuries in veterinary medicine, significantly impacting canine stifle joint stability and biomechanics, and subsequently, the animal’s quality of life. This study investigates the effectiveness of custom-made knee orthoses as a conservative treatment for recent cranial cruciate ligament ruptures in dogs. Two dogs with cranial cruciate ligament injuries were fitted with individualized orthoses, and their rehabilitation progress was monitored over 32 days. This study employed a four-scale method to measure body weight distribution across limbs and utilized owner questionnaires to evaluate lameness, gait, mobility, and physical activity. The results indicated substantial improvements in both dogs when they wore orthoses. Weight-bearing measurements demonstrated increased load on the injured limb by 0.97 kg and 2.23 kg for Dog 1 and Dog 2, respectively. Dog 2 achieved nearly symmetrical weight distribution by the end of the observation period. Shifts in body weight distribution between forelimbs and hindlimbs highlighted improved functionality; for instance, Dog 1 adjusted from 70% forelimb loading on day 1 to 62% on day 32, while Dog 2 improved from 60% to 55%. Similarly, shifts in lateral weight distribution showed notable reductions in asymmetry, especially in Dog 2, where contralateral load decreased from 59% to 52%. Owner-reported outcomes corroborated these findings, showing enhanced lameness scores, gait quality, and overall mobility. These results underline the potential of custom-manufactured orthoses as a valuable non-surgical approach for cranial cruciate ligament rehabilitation, emphasizing the need for further research in veterinary orthotics to optimize treatment strategies.

Behavioural problems in dogs are a major welfare concern for both dogs and owners, which can lead to relinquishment or euthanasia. As such, it is important to find ways to minimize the risk of development or severity of problematic behaviour. Such interventions should ideally occur early in the dog’s development and need to be widely and easily accessible. One way to implement such interventions, given modern smart phone use, is via an educational application (app). Here, we conducted a cross-sectional observational study where we sought to estimate associations between use of the Zigzag dog-training app (Zigzag Pet Care Services Ltd.) and the development and severity of problematic behaviours. We focused on a subset of the survey population (n = 367) who did no training at all (n = 194) or only used the app (did not attend formal classes or in person training; n = 173). Proportional odds ordinal logistic regression models were used to estimate odds ratios and 95% confidence intervals for a range of behaviours as a function of percentage completion of the first four chapters of the app while controlling for age, sex, health, and where the puppy was from. While sample sizes were relatively small and confidence intervals wide, 19 out of 21 odds ratio point estimates were in favour of severity being lower with increasing Zigzag app completion (the remaining 2 were marginally above 1). There was no good evidence that Zigzag increased the severity of any behaviours. On the contrary, there was reasonable evidence against the null hypothesis of no association in favour of Zigzag reducing the severity of familiar aggression, house soiling, chewing, barking, escaping, and noise fear. While causal effects cannot be claimed, overall, the reported associations are favourable and suggest that further study is warranted. Full article

A web-based quantitative survey tested pet owners’ preferences and willingness-to-pay for canine anti-pruritus therapies, and for improvements in pruritus-related quality of life. This survey was designed using findings from recent research into quality of life in pruritus, interviews with pet owners and veterinarians, and clinical and cost data. The survey was completed by 251 dog owners in the United Kingdom. A total of 46–47% were willing to pay to improve individual concepts of pruritus-related quality of life, including comfort, scratching behavior, and appearance. Instituting treatment to manage pruritus and the investigation of pruritus causes were considered important actions; safety and effectiveness were the most important attributes of therapy. Comparing the administration, effectiveness, safety, and costs of (unbranded) therapy profiles, on average, 63% preferred hypothetical tablet or injectable therapies (with higher cost and improved safety) over corticosteroid treatment for acute pruritus (p < 0.05). Over 50% of respondents preferred the hypothetical therapies in all tested subgroups, and results were similar for chronic pruritus. This research highlighted that many pet owners are willing to pay to improve their pet’s quality of life, and to receive comparably effective, yet safer therapies for the management of acute canine pruritus, regardless of insurance status. Veterinarians should consider discussing and offering newly available therapies for acute and chronic pruritus with pet owners where medically appropriate. Full article

Dogs are among the most popular pets worldwide, and ownership is increasing in many regions. Responsible pet ownership positively impacts animal welfare, yet little is known about the drivers of pet choices or their regional variation. To address this knowledge gap, a structured online questionnaire was developed to investigate the motivations, behaviours, perceptions, and demography of owners acquiring dogs. Quality control measures included content validity evaluation by independent experts and back-translation to optimize semantics. Non-probability convenience and purposive sampling was used to recruit respondents through social media and interest groups. In total, 2036 eligible responses were received. Three out of four respondents were female, which is a pattern reported in other regions. Mixed-breed dogs were the most popular, representing around 40% of the total, and non-commercial sources, such as shelters, were the predominant source for new pets (65%). In stark contrast to the UK, USA, and parts of Europe, brachycephalic breeds were the least popular of the purebreds. Poodles were the most frequently owned purebred in both HKSAR and MC. “Companionship for humans” was the most common reason for acquiring a pet dog, and strong agreement with the statement “I consider my dog part of my family” was almost universal (99%). Over half of respondents carried out no research before they acquired their dog (55%), and veterinary professionals were the least frequent resource used by the remainder. Our study reveals commonalities with other regions in drivers for, and perceptions of, pet dogs. Encouragingly from an animal welfare perspective, brachycephalic breeds were the least preferred type. Investigation of the drivers of this observation may be useful to encourage the acquisition of non-brachycephalic dogs in other regions. Overall, our study provides preliminary but valuable insights for developing targeted programs promoting responsible ownership in the region to enhance the well-being of both humans and dogs.

Gazing toward humans is fundamental in dog–human communication. This study aimed to characterize companion dogs based on their gazing behavior and to explore the potential links between gazing, personality (liveliness, confidence, aggressiveness, and attachment), emotional comfort provided to the owners, and breed. We observed 171 dogs in an ambiguous situation involving a moving stimulus, a remote-controlled toy car and gathered additional data with questionnaires. Our behavior analysis, based on gaze frequency directed at the owner and experimenter, identified four distinct clusters of dogs: low gazers, experimenter-focused gazers, owner-focused gazers, and frequent gazers. We found that experimenter-focused gazers exhibited lower levels of liveliness than frequent gazers and were reported to be less aggressive than low gazers and frequent gazers. Owner-focused gazers provided more emotional comfort to their owners than low gazers. Regarding breeds, 56.5% of German shepherd dogs were low gazers, compared to only 5.3% of golden retrievers. Age, sex, neutered status, and approaching the stimulus were not associated with cluster membership. These results highlight the complexity of dog–human communication, suggesting that personality, emotional factors, and breed shape how dogs seek guidance and support from humans or express anxiety.

Objective: This study aimed to compare pet owners’ knowledge of antibiotic use, understanding of antimicrobial resistance (AMR) and antibiotic practices for themselves and their pets to guide behavioral interventions to reduce AMR. Methods: A cross-sectional study conducted between March 2023 and December 2023 involved 1080 pet owners recruited from 16 veterinary clinics in Singapore. An anonymous self-administered survey assessed the participants’ knowledge of antibiotic use and AMR as well as their adherence to recommended antibiotic practices for themselves and their pets. McNemar’s Chi-square test was used to identify significant differences in the outcome variables between self and pets. The differences between the type of pet owned (dog owner/non-dog owner) were assessed using Pearson’s Chi-square test. Results: Among the 1080 pet owners surveyed, poorer knowledge of antibiotic use (46.3% vs. 33.2%; p < 0.001) and inappropriate antibiotic use (33.9% vs. 23.5%; p < 0.001) was more common for participants’ pets than for themselves. Compared to dog owners, non-dog owners had poorer knowledge of antibiotic use for their pets (poor knowledge, 55.2%; 42.4%; p < 0.001), but the knowledge of AMR occurrence and antibiotic practices did not differ between the dog owners and the non-dog owners. Conclusions: Pet owners have significantly poorer antibiotic use knowledge and antibiotic practices for their pets than for themselves. Compared to dog owners, non-dog owners have poorer knowledge of antibiotic use. Educational initiatives addressing pet owners’ knowledge deficits may improve their antibiotic practices for their pets and themselves, emphasizing the importance of cross-sectoral One Health planning.

Leptospirosis is a bacterial zoonotic disease that spreads through contaminated soil and water or directly from infected animals through urine. Although animal-to-human transmission is low, humans are most susceptible to contracting leptospirosis from these contaminated sources. This makes leptospirosis a public health concern, and therefore it is important to control these bacteria from spreading into the environment. A survey targeting Los Angeles County communities, in which a 2021 leptospirosis outbreak occurred, was sent out via groups on the online platforms Instagram and Facebook to gather dog and owner demographics. With 92 (90.2%) respondents having a primary veterinarian, it could not be determined what caused certain owners to have a greater vaccination rate than those who did not (n = 10; 9.8%). Overall, 69 respondents (68%), regardless of whether they had a primary veterinarian or not, reported not knowing of canine leptospirosis and 79 (77%) not knowing the signs to look for or that it is zoonotic. These data help provide a basis in terms of the status of dog owners’ knowledge of leptospirosis and how to begin to inform dog owners better about preventatives for this disease. Full article

Intestinal lymphoma is characterized by a malignant lymphoid neoplasm with multifactorial causes, variable clinical symptoms, and, in some cases, rapid progression. This article describes a case of intestinal lymphoma in a dog that had a history of diarrhea lasting two months, accompanied by episodes of hematochezia, which was treated using the CHOP 19 protocol. A seven-year-old male Golden Retriever presented to a veterinary clinic with clinical signs of diarrhea, prostration, and the presence of bloody feces, as reported by the owner. Initial examinations, including hematology, serum biochemistry, and imaging, revealed an abnormal structure in the intestinal region. Considering the circumstances, a surgical procedure was conducted with the aid of a trans-surgical frozen section biopsy. This biopsy aimed to verify the presence of the neoplasm, assess the suspected diagnosis, evaluate the viability of the surgical margins, and determine the possibility of expanding the surgical area. An enterectomy with enteroanastomosis and trans-surgical biopsy was performed, leading to an initial diagnosis of intestinal lymphoma. The tissue fragment was sent for immunohistochemistry, which ultimately confirmed the diagnosis of intestinal T-cell lymphoma. The patient underwent the CHOP protocol for 19 weeks, but during the maintenance phase, abdominal ultrasound examination findings indicated tumor recurrence. Despite being informed of the potential benefits of further chemotherapy, the owner opted not to continue treatment for the animal. Frozen section biopsy can help with diagnosis during surgery, avoiding more invasive procedures and the removal of lymph nodes, since in some cases, the systemic treatment of the disease is recommended.

Reduced efficacy of oral diuretics in the treatment of congestive heart failure (CHF) can be secondary to reduced enteral drug absorption. The aim of this study was to determine the efficacy of subcutaneous (SC) furosemide administration to control the signs of refractory CHF in dogs and cats and to assess the feasibility of this route of administration. The clinical records of 13 dogs and 17 cats with a history of refractory CHF treated with subcutaneous (SC) furosemide were reviewed retrospectively. Administration of SC furosemide was offered as an alternative therapy when animals experienced an unsatisfactory clinical response to oral diuretics despite multiple dose adjustments and when, for this reason, pet owners were considering euthanasia. The satisfactory control of the animal’s breathing rate and effort and overall pet owner’s satisfaction were observed in all cases. Following administration of SC furosemide, the median survival time was 106 (95% CI: 22–154) days in dogs and 89 (95% CI: 35 to 749) days in cats. This study showed that furosemide administered subcutaneously appears to be an efficacious and feasible therapeutic option for providing control of the signs of cardiac congestion in both dogs and cats with a previous unsatisfactory response to oral diuresis.

Feeding raw meat to cats and dogs has become a common practice in Western countries. Many pet owners cite their pets’ wild carnivore ancestry and believe raw meat diets are healthier, citing higher nutritional value, a lack of processing, low-carbohydrate content, and/or the presence of whole ingredients. However, due to the risks associated with raw meat-based diets (e.g., microbial contamination, nutritional imbalances) and growing concerns about food sustainability, most nutritional specialists and public health stakeholders question the practice of feeding raw meat. In this context, the vast majority of owners’ claims regarding the beneficial health effects of raw meat diets lack scientific substantiation, while professional advice primarily focuses on risks, often overlooking potential positive health effects. To better understand the effects of raw meat diets on the health of cats and dogs, this review summarises the latest scientific evidence and discusses both the potential health benefits and the risks associated with these diets.

The purpose of this study was to assess the practical implications of supplementing soluble fiber in the diet of dogs. Dogs with a history of managed or active chronic enteropathy were randomized to receive either wheat dextrin (fiber group) or maltodextrin (placebo group) mixed with food once daily for 28 days. Owners recorded a daily fecal score one week prior to and during the supplementation period. Shallow shotgun sequencing, quantitative PCR abundances of core bacterial taxa, and short-chain fatty acid (SCFA) concentrations via gas chromatography/mass spectrometry were performed on fecal samples collected before and after supplementation. Seventeen dogs completed the study (fiber group: nine dogs; placebo group: eight dogs). The change in fecal score differed between groups, with the fiber group developing softer stools (p = 0.03). Alpha diversity, quantified PCR abundances of the SCFA-producing taxa, and fecal SCFA concentrations were not different after supplementation in either group. Fecal microbial communities differed between baseline and day 28 for fiber and placebo groups (p = 0.02, respectively); however, the size effect (ANOSIM R = 0.18 and R = 0.26, respectively) was minimal. In this small group of dogs fed variable commercial diets, the additional intake of wheat dextrin powder supplement was well accepted, but had minimal discernable clinical benefit, and could soften stools.

There are global concerns regarding the transmission of antimicrobial-resistant pathogens from animals to humans. Especially, companion animals are increasingly recognized as a potential source due to their close interactions with people, despite a limited number of reported cases. Although, social demands regarding comprehensive surveillance for antimicrobial resistance (AMR) among companion animals are highlighted, there is a lack of a relevant system in South Korea. In this regard, we conducted preliminary investigation on antimicrobial use (AMU) among small animal clinics, along with veterinary practitioner’s knowledge and attitude regarding this issue in South Korea. We collected data on 684,153 antimicrobial prescription visits for canine and feline patients from 2019 to 2022 at 100 veterinary facilities in South Korea, using electronic medical records. To evaluate antimicrobial use (AMU) and facilitate comparisons across institutions and time periods, we developed the Defined Daily Dose for Animals (DDDA) and the Defined Animal Daily Dosages per 1000 Animal-Days (DAPD). In addition, we conducted an online survey of 362 veterinary practitioners, which included questions on their perceptions, attitudes, and practices regarding antimicrobial prescriptions. Simple frequency analyses were performed to examine temporal trends, regional differences and variations by facility size in AMU, and to summarize survey responses. Descriptive analysis using data from 100 veterinary clinics revealed a rising trend in AMU between 2019 and 2022, with higher usage observed in larger clinics and non-capital regions. DDDA values for dogs were generally higher than for cats. Survey results highlighted that, while veterinarians exhibited high awareness of AMR, prescribing practices were significantly influenced by clinical judgments and owner demands, often deviating from established guidelines. The adoption of an electronic veterinary prescription management system (e-Vet) was proposed to enhance antimicrobial stewardship. However, concerns regarding the system’s efficiency and administrative burden were prominent. To our best knowledge, this study provided DDDA for companion animals for the first time in South Korea. Although the indicator should be improved with more comprehensive data and expert opinion, our study showed that it enables reasonable situation analysis regarding AMU in companion animals. The identified factors that affect veterinarians’ prescription practices can also be used to design an effective strategy for promoting appropriate antimicrobial usage. Full article

Can black soldier fly (BSF) larvae be a protein substitute for managing adverse food reactions (AFRs) in dogs, specifically those with dermatitis? We evaluated BSF larvae’s safety, tolerance, and effectiveness as a novel protein source in dogs with AFRs. Sixteen dogs, including eight healthy controls and eight diagnosed with AFRs, were fed a diet containing BSF larvae for four weeks. Skin conditions, including dermatological lesions and Pruritus Visual Analog Scale (PVAS) scores, and gastrointestinal signs, including relevant clinical signs, stool consistency, and hematological and biochemical parameters, were monitored. No significant gastrointestinal side effects were observed. The control and AFRs groups maintained stable body weights, while stool consistency scores did not change significantly. Moreover, skin reaction data obtained before the study were collected through interviews with the owners. The mean PVAS scores in the AFRs group were significantly higher (p < 0.05) during the self-control period (6.0 ± 1.6) when compared with other periods. However, no significant differences (p > 0.05) were observed between the pre-study baseline (2.0 ± 1.1) and scores at 2 weeks (2.3 ± 1.5) and 4 weeks (2.4 ± 1.2) of feeding with BSF-based food, which indicated that BSF larvae did not exacerbate pruritic symptoms. Hematology and blood chemistry remained within normal ranges in all dogs, indicating no adverse effects on overall health. BSF larvae were well tolerated by AFR-affected and control dogs, with no adverse clinical outcomes. The findings suggest that BSF larvae may offer a better, sustainable alternative protein source for managing AFRs in dogs, particularly in those on hypoallergenic diets. Further long-term studies are needed to confirm these results and assess the broader implications of BSF larvae diets on canine health. Full article
