My dog likes z/d. Is there a cheaper Hill's alternative at Petco?

Thats funny! Most dogs don't want to eat the Z/D! I don't think they have a food that tastes exactly like the Z/D at non-prescription price but you could try any of the science diet dog foods - all of which are very palatable and she may like. For just a general food, I like science diet adult for dogs over 1. Once she is over 7 years old, I recommend to switch her to the senior diet. It is perfectly safe for her to eat the z/d long term although that would be expensive for you. I hope this helps!

My dog has protein intolerance. Need Hill's Z/D food alternatives?

Without a full diet history it is impossible to prescribe a diet. Hills z/d is a hydrolyzed formula where all the proteins have been broken down (akin to being pre-digested) into small pieces so the immune system should not react to them and so should resolve the food intolerance symptoms, it is easily digested and highly absorbable by even the most sensitive bowel. A similar, hydrolyzed option is royal canin hypoallergenic or anallergenic and many pets find these extremely palatable. Some cases can do well on a 'novel protein diet' of home prepared food based on a protein source which she has never eaten before. This should be formulated only by a specialist nutritionist - tufts university clinical nutrition team are available by phone or appointment to help with this but it can be extremely expensive and time consuming to feed such a specific and strict diet and commercial brands are often more successful in resolving symptoms in the long term

My cat needs Hill's k/d prescription food, out of stock. Where to buy?

Thank you for using Boop by Petco. Many veterinarians will carry Hill’s prescription diets. I recommend calling to see who may carry it. As it is a prescription diet they may require a prescription or call from your veterinarian in order to sell the food.

My dog needs Hill's i/d. Cheaper digestive diet alternatives?

Hill's i/d is an intestinal diet that is easy for a dog to digest. There are other intestinal diets that might be less expensive, like Science Diet sensitive stomach. Ask your vet for his/her recommendation for a more affordable diet before deciding to change. Also, ask your vet if you could just add extra fiber to your dogs diet, like some canned pumpkin.

Is Hills i/d chicken stew good for sensitive dogs, sugar included?

Thanks for using Boop by Petco! Yes, that diet is great and I do think you should proceed to add it in Chloe's diet. I have had plenty of clients who use that diet and are very happy with it. Good luck and have a good night!
