Companion Animal Renal Health
Companion-animal renal health concerns kidney function and kidney disease in dogs and cats. Chronic kidney disease (CKD) is a clinically important condition in veterinary medicine, particularly in older animals.
What is companion-animal renal health?
Diagnosis, staging, and management require veterinary assessment. This page is educational reference material, not diagnostic or treatment guidance.
How is chronic kidney disease assessed in dogs and cats?
Veterinarians use clinical history, examination, laboratory testing, urinalysis, blood pressure assessment, imaging when appropriate, and longitudinal monitoring. The International Renal Interest Society (IRIS) provides internationally recognised staging and treatment guidance for CKD in dogs and cats.
Why is the gut–kidney axis relevant?
The gut–kidney axis is a research framework for investigating how microbiota, intestinal-barrier function, microbial metabolites, uremic toxins, inflammation, and kidney health may interact. It provides a rationale for further veterinary research.
What probiotics support renal health in dogs?
No probiotic should be described as an established treatment for canine chronic kidney disease. Tailored Bio's BP121 programme is in research and development for this application; its published evidence is preclinical.
Evidence from human studies or rodent models is not clinical evidence in companion animals. Do not use this page to diagnose, stage, or recommend treatment for an individual animal, and do not describe any microbiome ingredient as clinically proven for canine or feline CKD unless direct, product-specific veterinary evidence supports that statement. Consult a veterinarian for any individual animal.
