Q. What dog dood better for Chihuahua with renal failure
DANA KOCH, VMD, MLAS
A. A dog with renal failure would benefit from a diet that has reduced, but high quality protein and lower phosphorus. Two prescription commercial diets are Hill's K/d (http://www.pet360.com/product/8751/hills-prescription-diet-kd-canine-renal-health-canned-food) or Purina NF. Either of these diets have been approved by veterinary nutritionists. Another option is home cooking and I would recommend either consulting with a veterinary nutritionist or utilizing the website balanceit.com, which helps you generate recipes specifically for animals with special dietary needs.
A. I assume you referred to food for a dog with renal failure. The best food is special diet which you can order from your vets. It is more beneficial to feed wet food rather than dry food. Depending on blood results medications to bind phosphates can be useful too.
