As dogs age, they may require food designed to help reduce nutrient excesses that could be harmful to their system. For example, high levels of sodium, phosphorus and protein can cause increased workload in the kidneys and heart. Kidneys are very important to the health of your dogs because they remove waste substances from the blood and maintain the normal balance of fluid and minerals within the body. Once kidney damage occurs, the consequences are usually irreversible. The heart is the most important organ in your pet's body, and factors such as age or weight may affect its function. Poor heart health can affect your dog's lifestyle and mood. Because the food your dog eats plays an important role in his or her overall health and well-being, at Hill's, nutritionists and veterinarians developed clinical nutrition especially formulated to support your older dog's kidneys and heart for overall health. Plus, with the S+OXSHIELD seal of confidence, the Aging Care formula meets specific nutrient standards shown to promote a urinary environment that helps reduce the risk of struvite and calcium oxalate crystals.

Key Benefits
  • Clinical nutrition especially formulated to support your older dog's kidneys and heart for overall health.
  • Reduced phosphorus helps minimize stress on aging kidneys and reduced sodium helps maintain normal blood pressure.
  • Reduced protein and targeted levels of high-quality protein help decrease kidney workload.
  • Optimal fat levels to reduce pancreatic workload, plus increased levels of omega-3 fatty acids and controlled calories support kidney health.
  • Aging Care recipe has not changed—it offers the same great taste and benefits as it did prior to the introduction of the S+OXSHIELD seal of confidence.

Transition Instructions

A gradual transition to a new pet food is important to avoid digestive upset. To transition, mix your pet’s current food with the new food. Over 7 days, gradually decrease the amount of the current pet food while increasing the amount of new pet food. In some cases, your veterinarian may recommend no transition or a shorter transition time.

    New prescription food for our Beagle

    By on

    Prescribed for our 10 year old beagle with early stage kidney disease. She seems to like the flavor and now used to the larger kibble as she previously enjoyed “small bites” formula. We add plain nonfat Greek yogurt in the morning and canned pumpkin in the evening to keep her stomach less reactive. So far so good.

    Sorry, My dog will not touch it!

    By on

    My vet had me switch our little baby to this because her kidney function was not the best. She had been on Purina EN because of frequent bouts of pancreatitis. Unfortunately, she left it in the bowl for 3 days, and the vet said to put her back on Purina. AFTER I had given a new bag of the Purina to a local shelter. My bad!

    Hill's Prescription Diet g/d

    By on

    My veterinarian recommended this food for my 18 lb. cavalier because of heart and kidney disease as well as a bout with pancreatitis. It is helping but he doesn't like it at all and I have a difficult time getting him to eat it. He will only eat it if I add something to it to make it more palatable. The kibble is too big and hard and I have to crush it. I wish there was a better alternative.

    Hill’s Prescription Dry G/D very Dry

    By on

    Have to cover the Dry Dog food with water or my dog won’t eat it. It’s apparently so dry that when he chews it dry flakes go down his throat and he coughs. The water really helps and plumps up the dry food so he’ll eat eat. Sometimes still a little crunchy and sometimes mushy. Anyway, the dog is happy!!

    fast shipping!!

    By on

    My shipment came lightning fast. Even having to get the vet to approve it, it came within 2 days. I do wish the flavor was more appetizing to my senior dog... she does not seem to like it. Ironically, my young dog loves it and tries to steal it from her older sister!!! :)
