Canine chronic kidney disease requires specific dietary management to reduce uraemic toxin accumulation and slow progression. Appropriate nutrition is one of the most impactful welfare interventions.
CKD causes chronic welfare deterioration through progressive uraemia — accumulation of metabolic waste products that cause nausea, lethargy, and eventually neurological dysfunction. Dietary management that reduces phosphate accumulation and uraemic toxin load directly reduces this welfare burden. Dogs that transition successfully to appropriate renal diets show improved appetite and energy — a welfare gain from reducing the uraemic state. The challenge is palatability: renal diets are formulated for health benefit rather than palatability, and many dogs refuse them. Finding formulations the dog will eat while meeting nutritional requirements is a practical welfare challenge requiring patience and veterinary nutritional advice. Subcutaneous fluids administered by trained owners at home provide welfare benefit in dogs with dehydration contributing to their uraemic signs.
