Protein is widely regarded as the most important macronutrient in human and animal diets. However, if your canine companion suffers from kidney disease, liver disease or certain kinds of stones found in the urogenital tract (bladder or kidneys) then it is better to feed a diet that is low in protein. Why? Your liver and kidneys break down proteins as part of normal metabolic processes. However, if your dog has lower kidney or liver function, it is important to avoid excess proteins as it causes the organs to work overtime. Furthermore, excess protein in a dog’s diet can change the pH of urine, which can be detrimental to the dissolution of certain kinds of bladder or kidney stones. If your veterinarian recommended a low protein diet, this is an excellent tool to choose the most appropriate diet for your companion.
