Limited ingredient diets come with one major benefit - pet parents are able to identify exactly what goes into their dog's body and avoid any specific ingredients. While a suitable diet for many dogs, LID diets can also be great for dogs with food sensitivities.

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!

Thank you for using Petco Pet Education Center, formerly Petcoach. 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.

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

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.

I'm very sorry you lost Lani. Yes, it is true there was a recall for a high level of vitamin D, but there are many dog foods that have had recalls for a number of different reasons. Overall, it has proven to be an excellent food, which is why we sell it. They do run food trials, have veterinary nutritionists on staff, and meet AAFFCO standards, which none of the boutique and grain free diets do. I know you won't agree with my answer, and I am so sorry that you lost your dog.
