This food is great. Lulu loves the taste of the canned ZD. I tried giving her the dry but because she is so small the kibbles are too big for her try to chew. Lulu was put on ZD because she tested positive for allergies to wheat, rice, corn,milk, and beef. She has envionmental allergies also but she doesn't scratch near as much as she used to.

I like this one better than the Royal Canin version that my dog couldn;t care less... Even though is the same price my dog still doesn't love eating it, I can tell it smells better and has smaller pieces which has worked better for my 4 month puppy.
I wish there was a way to make this formula better since it's my only choice, and it's hard to be forcing my dog to eat it, she can go for a couple days withput eating any before eating this food but then she gets sick... I will recommend it only as a last resource, Works better if mixed with the Wet version of it, I use it as a treat to bribe Buggy to eat

9 years and going strong

By BigBooza

from College Station, TX, USA

Comments about Hill's Prescription Diet z/d Ultra Allergen-Free Canine Dry Food:

My Neapolitan mastiff has allergies and has been eating z/d for 9 years. It's the only hypoallergenic diet that keeps her skin and ears under control. My only complaint is the price. Forty pounds a month adds up fast! She's now almost 13 and very happy.

z/d ultra hypoallergenic dog food

By megs

from dfw, tx

Comments about Hill's Prescription Diet z/d Ultra Allergen-Free Canine Dry Food:

Switching my dog to z/d ultra from another prescription hypoallergenic dog food enabled us to eliminate several medications from his daily regimen and greatly reduce the frequency & severity of his allergy flare-ups. He also seems to prefer the taste of the z/d over the previous brand.

A Cure for the Itch!

By TLCRees

from Jacksonville, FL

Comments about Hill's Prescription Diet z/d Ultra Allergen-Free Canine Dry Food:

My dog has food allergies and has been on z/d ultra for the past 4 or so years. The price of the food is a little high, but it beats having to go to the vet every other month for exams, antibiotics, etc. My dog loves it and even enjoys the treats version they have.

Expensive But Good

By jlm9243

from illinois

Comments about Hill's Prescription Diet z/d Ultra Allergen-Free Canine Dry Food:

Overall I believe that the product costs way too much money, however it works well for my dog. Since being put on this dog food by the vet, she has not had 1 ear infection.
