Studies suggest that feeding your dog a diet low in phosphorus may help slow the progression of kidney failure by reducing mineral deposits in the kidneys. And while there’s no conclusive proof that low-protein diets slow CRF in dogs, your pet may feel better on such a diet. Low-protein diets generate fewer nitrogenous wastes – high levels of which can cause nausea and vomiting in dogs with kidney disease. A cautionary note: low-protein diets, if not carefully managed, can lead to malnutrition. So be sure to consult your veterinarian/nutritionist before making any such dietary changes. 

Above all, keep a watchful eye. Report any changes in your dog’s eating, drinking, and elimination habits to your veterinarian/nutritionist. Such changes may alert your veterinarian/nutritionist to the possibility of kidney disease – or help your veterinary practitioner adjust treatment if therapy has already begun. 

With kidney disease, your dog becomes less alert, loses its appetite, and may vomit. Take your dog to your veterinarian if it shows any of the following signs that sometimes (but not always) point to kidney disease: 

1. Increased thirst and urine volume 
2. Weight loss 
3. Weakness and exercise intolerance 
4. Tendency to bleed or bruise easily
