As a preventative meaure, a diet individually chosen for your dog can help reduce the occurrence of bladder stones. As each dog can be prone to develop a different type of bladder stone, advice on the subject that applies to your pet is requires consultation. Especially, as diets may vary greatly in content. For help, present a fresh urine sample to your vet. He/She will can test and analyize the sample, and use it to help you choose a suitable product for your pet. Renal dog food is best purchased through a vet practice, as individual products are designed to cover specific varieties of bladder stones, and are of good quality. Self-made diets are difficult to produce and time-consuming. For that reason, commercial renal food is usually preferred by pet owners.
