The appropriate diet for dogs with kidney disease varies but most focus on lowering the salt, protein and phosphorus in the dog's food, according to WebMD and Hill's Pet Nutrition. A veterinarian can usually give more specific advice depending on your pet's needs.
In some cases, owners can keep their dog's current brand of food but need to choose another selection within the brand's offerings. In other cases, a prescription food brand will need to be chosen such as the Hill's Prescription Diet for dogs with kidney disease, notes WebMD and Hill's Pet Nutrition. Water intake is also important for dogs with kidney disease, and dogs should be given flavored broth as well as water if the dog's water intake is too low, reports the College of Veterinary Medicine at Washington State University. The broth should not have added sodium.
When the dog food has less phosphorous, fewer kidney disease symptoms present, notes Hill's Pet Nutrition. When protein levels are lowered in the dog's food then the dog's body will find a normal acid-base balance. It is important for dogs with kidney disease to eat specialized food because kidney disease is not curable. The kidneys in a dog with kidney disease will continue to decline, and specialized food can help slow the process and make the dogs feel more comfortable, according to the College of Veterinary Medicine at Washington State University.
