The use of Prescription Diets does require you to have a relationship with your veterinarian ~ and all this means is you take great care of your pet!! Vaccines are up to date and you see your veterinarian at least once a year! Using preventative health feeding practices can help prevent, avoid or slow down disease!
Medical diets are the ones formulated for dogs with health problems, from vexing but garden-variety conditions such as itchy skin or digestive issues, to more serious health problems such as cancer or kidney disease.
Kidney diets – these diets are excellent for managing the symptoms of kidney failure, and at least one study claims that life expectancy is increased in dogs fed such diets
Urinary tract diets – designed to minimize, prevent, dissolve, or otherwise have an effect on the formation of bladder stones. In dogs, stones are usually either struvite or calcium oxalate, though there are a few other more unusual stones such as urate and cystine, and stones may contain combinations of mineral types. This is a case where a vet’s reading of your dog’s test (urinalysis) results would be critical for effective prescribing. Some breeds are prone to one or more types of stones (for example, urate in Dalmatians, struvite and calcium oxalate in Schnauzers).
Cardiac diets – The main feature of cardiac diets is low sodium
Joint health diets – Numerous studies have shown glucosamine and chondroitin to be beneficial supplements
Oral/dental health – formula will actually remove tartar from the teeth.
Diabetes diets – The mainstay of diabetes treatment in pets has always been a high-fiber diet, which theoretically slows digestion and maintains a steadier blood glucose level. Recent research in cats has dramatically reversed this thinking, with high-protein, high-fat, very low-carbohydrate/fiber diets
Obesity – provide between 200-300 calories per cup of kibble, compared to 300-400 for most maintenance
Geriatrics – these foods are lower in fat and calories than maintenance foods
Allergies and gastrointestinal disease – to treat allergic skin disease, while others address food intolerances, true food allergies, and a variety of GI ailments. Food intolerances and allergies in dogs tend to manifest in two primary ways: skin disease and gastrointestinal disease. Allergic skin disease (such as rashes, itchiness, ear infections, and lick granulomas) is most commonly caused by inhalant allergens (dust, pollen, etc.), but dogs can be truly food-allergic. Diarrhea and other GI signs can be caused by a food allergy, but are more often the result of a food intolerance, rather than a real immunologic reaction to a food component, which is the hallmark of a food allergy
