Two adult dogs with the same owner were intoxicated by ingestion of fertilizer composed of residual plant material of the castor bean plant (Ricinus communis L.). Both dogs died within 2 and 3 days, respectively, after the first signs of vomiting and abundant hemorrhagic diarrhea. Toxicologic and histopathologic examinations were performed on different organs. Histopathologic examination of the kidneys revealed tubular degeneration and necrosis and membranous glomerulonephritis. Additionally, myocardial degeneration with localized inflammation, lymphoid necrosis, and depletion in the spleen and mesenteric lymph nodes and hemorrhagic ulcerative gastroenteritis were found. The 2 cases could be used to elucidate the lethal dose of ricin and the histopathologic lesions in dogs.

A canine model of reversible urethral sphincter insufficiency.

Animal Model Exp Med

January 2025

Urology and Nephrology Research Center, Research Institute of Urology and Nephrology, Shahid Labbafinejad Medical Center, Urology Department, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

This study developed an animal model with internal and external urethral sphincter insufficiency by bypassing the sphincter without major damage so that the animal under study can return to normal life after the study. There is a need for a reliable, applicable, and reproducible animal model for studying urinary incontinency disease due to incorrect sphincter function. Seven adult male dogs were used for this study.

Research has shown various hydrolyzed proteins possessed beneficial physiological functions; however, the mechanism of how hydrolysates influence metabolism is unclear. Therefore, the current study aimed to examine the effects of different sources of protein hydrolysates, being the main dietary protein source in extruded diets, on metabolism in healthy adult dogs. Three complete and balanced extruded canine diets were formulated: control chicken meal diet (CONd), chicken liver and heart hydrolysate diet (CLHd), mechanically separated chicken hydrolysate diet (CHd).

Combining genomics and epidemiology to investigate a zoonotic outbreak of rabies in Romblon Province, Philippines.

Rabies is a viral zoonosis that kills thousands of people annually in low- and middle-income countries across Africa and Asia where domestic dogs are the reservoir. 'Zero by 30', the global strategy to end dog-mediated human rabies, promotes a One Health approach underpinned by mass dog vaccination, post-exposure vaccination of bite victims, robust surveillance and community engagement. Using Integrated Bite Case Management (IBCM) and whole genome sequencing (WGS), we enhanced rabies surveillance to detect an outbreak in a formerly rabies-free island province in the Philippines.

Background: Age-related changes in physiological parameters are crucial in understanding the health and performance of working dogs, particularly those in demanding roles such as military and law enforcement. However, limited research exists on how aging affects the hematological and biochemical health of these dogs.

Aim: This study aims to characterize age-related variations in hematological and biochemical parameters in working Belgian Shepherd dogs to provide insights that could inform health management strategies for these animals.

Ultrasonographic renal length-to-aorta ratio is an ideal reflection of renal health in dogs. Earlier studies have highlighted the need for breed-specific reference intervals for this parameter. The aim of this study was to establish a breed-specific reference interval of kidney length to aorta ratio (KL:Ao) in Chippiparai dogs, a breed of Indian sighthounds.
