Chronic enteropathy in dogs is a common clinical problem with a poorly understood pathogenesis. Learn how transcriptomic studies are providing new insights into the mechanisms that contribute to clinical signs of chronic enteropathy.

Learn how immune system dysregulation and reduced tolerance to otherwise innocuous food components result in development of food allergies in dogs.

Scientists’ understanding of the host-microbiome relationship has evolved substantially during the past 15 years, revealing a complex interplay among diet, host genetics, microbiota, and health.

Chronic enteropathy in dogs and cats is characterized by overlapping unspecific features that often result from persistent dysbiosis and irreversible changes in intestinal function. Learn why different patients respond differently to therapy.

Discover what is currently known about the role of acute intestinal injury in the development of chronic enteropathies and food allergies in dogs.

Epithelial barrier dysfunction, oxidant injury, and inflammation are common to both atopic dermatitis and chronic inflammatory enteropathy in dogs. These shared features are attractive targets for nutritional approaches to patient management.

An overview of immune complex-mediated glomerular diseases of dogs and cats, including glomerular anatomy, classification, causative agents, pathogenesis, diagnostics, and clinical implications.

Progression of chronic kidney disease in cats is multifactorial, poorly understood, and highly variable. Learn more about the eight factors that have been implicated in renal inflammation, fibrosis, and disease progression.

Arginine deficiency leads to severe metabolic abnormalities and immune dysfunction in human, feline, and canine patients. Learn about arginine deficiency syndrome, its consequences, and arginine replacement therapy in human medicine.

Is feline idiopathic cystitis merely inflammation of the bladder urothelium? What is the etiology of the inflammation? Learn the answers to these questions and others, including how to help affected cats.
