Food sensitivites and intolerance are potentially serious problems that can result in sensitive or irritated skin, coat and ear conditions or even gastrointestinal upset. Dogs that have a food sensitivities or intolerance, also called adverse reactions to food, typically experience an abnormal response to the protein in the food.

Hill's Prescription Diet z/d Canine Ultra Dry Dog Food Customer Reviews

Hill's Prescription Diet z/d Canine Ultra Dry Dog Food 4.8 5 49 49
This food is very palatable Our dog was recently diagnosed with food allergies and our veterinarian wanted us to place her on Z/D Ultra. She was on a raw diet before the switch over and we were concerned about her taking to this kibble but she loved it! Not only does she love it, she has transitioned without any side effects. I would definitely recommend this product to anyone who has a pet with allergies December 30, 2013
She likes the food and it resolved her allergy & digestive issues My ten year old lab, Babe, has had digestion and allergy issues her whole life. I've tried everything including a home-made diet of oatmeal & whey protein with GNC canine supplement that worked until she refused to eat it. So my vet put her on Hills z/d diet which is very expensive, but she likes it and it has relieved her intestinal and allergy problems. I just made my first purchase of it from Chewy and was pleased with how quickly I received my first shipment, and with the price which was considerably better than what my vet was charging... even before getting $15 (15% off) my first order for signing-up for autoship. December 17, 2013
I was really surprised. I was surprised because I did not know that z/d ultra is a prescription dog food sold only that way. It is a great dog food that has helped my dog over come her allergies. We had been trying every thing to stop the itching, as well as stomach problems. I would recommend this to everyone with a pet with these problems. Thank you HILLS! December 9, 2013
Good for allergies! I have a Westie who is allergic to rice, lamb, eggs etc. This food he really likes, smells decent and really has helped his itching. Not cheap but worth it. Kibble is a little big for a small dog but he has no problem - just takes him longer to eat it which is probably a good thing! December 7, 2013
The one that works. My boy Tucker has severe allergies and this food is the only one that I have found that works for him. Highly recommend trying it. November 19, 2013
Order Food Online Being on prescription diet food means that you always have to go to the vet to pick up food. We buy big bags of food so this can be a hassle. delivered directly to our door and we greatly appreciate it!! We received a quality product and our dog loves it! Thanks!! November 19, 2013
Best price in town Best price and free shipping no need to run around town. October 27, 2013
Great food for highly allergic dogs I have a 13 yo rescue Maltese. He has severe allergies to EVERYTHING. This is the ONLY food he is able to eat. Ever! October 27, 2013
Another great Hills product, without the allegens my canine suffers from Science Diet Z/D Ultra is a wonderful and welcome relief for my Chessie who suffers from food allergies with painful skin problems. She is doing much better since on this diet. October 23, 2013
This product really helped my dog's skin allergy. My poor Maggie Mae had weeping scabs everywhere and was losing her beautiful border collie coat. We tried other hypoallergenic dog foods but this is the one that works. I resisted putting her on it because of negative comments online stating that vets just sell it to make money. Can't be true my vet gave me a RX to buy online and a friend of ours who is a vet in California also gave it the thumbs up. It's pricey and really zaps my budget (have 3 dogs including a rescue) but for my girl's well being I spend the extra $$. I'm pleased at how beautiful Maggie's coat looks and she loves it. Chewy makes it easy to order and their representatives are so helpful. I was happy with my purchase. October 23, 2013
No more ear infections! My standard poodle Nikita was plagued with ear infections for a very long time. Finally our Veterinarian prescribed Hills Prescription Diet Z/D Canine Ultra, and her ears cleared up immediately. She has not had any itching or problems at all with her ears since we changed her diet. It is a blessing! And I have to add the offered the best price and super fast shipping for a great product. Doesn't get much better than this! October 20, 2013
