by aabrodal1 Excellent Prescription Food
My yellow lab, Nixon, has severe food and skin allergies. He has been on medication for allergy infections and multiple diets to help with his food allergies. We have tried him on three different prescription foods and none have worked as well as the Hills Science Diet Z/D food. He still takes a regular dosage of allergy medication for his skin, but in conjunction with the Z/D formula it has helped clear up his skin problems along with the constant upset stomach. Since switching to Hills Nixon is much more regular and doesn't require me to constantly take him out for bathroom breaks. I am extremely happy with this food.

Rated 5 out of 5 by HeatherA A must if your dog has allergies!
I spent a good two years trying to find my dog a food that would help with his allergy/skin problems. I tried everything from holistic to grain free! Nothing worked! I ended up going to the vet and he put my dog on this food! Hydrolyzed Protein System made by Hills, it is so much better for my dogs system! His allergy and itchy skin problem has cleared up and I love this dog food!

Rated 5 out of 5 by DeanD How can anyone not recommend this product?
I cannot begin to tell you how brutal it's been while I watched my little yorkie suffer through her food allergies over the past 3 years!
I've had saliva testing, thyroid testing, blood allergy testing, skin testing, homeopathic meds, antibiotics, allergy shots, etc.. Nothing worked.. (Thank god for pet insurance!!!!)
I originally didn't give this product a chance b/c the kibble size is tooo large, but I soak it in diluted apple cider vinegar and olive oil with warm water so it's easy to break down. Yum!! .. no.. more like yuck! lol!, but she eats it!
I stayed the course with this one, and after 6 weeks, the dry spots finally went away and she may itch a tiny bit, but little and normal tolerable stuff. No more hair loss with bloody faces from rubbing her head into the carpet!!! yuck!
The funny thing is that I was able to get my hands on the new APOQEL drug for dogs that stops the itch.. It's supposedly safer than pred and the other med and specifically targets the itch ONLY. Well, it's not available in this country yet b/c it has been held up at the manufacturer.. I ended up ordering from the UK and have it on hand "JUST IN CASE".. lol!
I'm assuming I won't be needing it any time soon...
I only wish the kibble of this food was smaller so I didn't have to make it mushy for her, but hey; I'll do what I have to do!! Anything is better than watching your little doggie suffer in an ungodly fashion!
Now I just need to know if she can stay on it for the rest of her life?? Does it provide her with enough nutrients that she needs as she gets older?

Rated 3 out of 5 by thebestdogBFF The z/d dog food relieved his severe itching/chewing.
This is the third bag of the Hill's z/d dog food. It was recommended by our veterinarian to see if his excessive itching/chewing was related to a food (protein) allergy. It was completely effective in relieving his excessive itching/chewing. I did notice that his stools became much softer and the frequency was reduced from 2 to 1 stool per day- which the vet said is normal. Being a German Shepherd dog ( almost 9 years old) he has had digestive issues in the past. Although the food is very expensive, I was willing to pay it for his relief of allergy symptoms. Unfortunately, he now is very reluctant to eat it and often refuses it completely. He has had many dietary changes recently which may have contributed to this. Otherwise, the food was effective for him and I hope to continue with it.

My pup is allergic to just about everything under the sun! From environmental factors to food allergies, he is very uncomfortable constantly. Scratching almost incessantly, up until we bought this food. He is finally finding some relief!

Rated 5 out of 5 by Nan84 This product has helped prevent ear infections for my dog with food allergies
My 3 year old lab, who is an outside dog, was getting ear infections every 6-8 weeks before we started using Hill's Prescription DietZ/D. Our doctor put her own this diet because he thinks that she has food allergies causing her to get these frequent ear infections. Once we completely switched to the Z/D diet she has not had a single ear infection. She was also in the obese category per her doctor, but she has lost 14 pounds since starting this diet, and she is now in the healthy range for her age and type. I would highly recommend this dog food and using Chewy.com to order your food because it's cheaper then at the vet or any other store and it is shipped right to your home. I have set up a bag of food to be delivered every 6 weeks, and I am looking forward to not having to worry about remembering to go to the vet to pick the food up. This is a great place to order your pets food from!

Rated 5 out of 5 by ecad Seems to be working!
My dogs were a little hesitant to eat the food at first. It has a very pungent odor. But, after a couple of weeks I can already tell a diffence in my dog with severe food allergies. He is scratching less, sores are gone and the piles of hair are almost gone from my home. I just wish the food came with a smaller price tag!

Rated 5 out of 5 by Duffy14 This product has releived my dog's severe allergy symptoms.
Our dog had suffered for years with chronic skin and ear infections due to multiple grain allergies. Our Vet recommended Z-D for the hydrolized proteins and after 1/4 bag our poor Duffy began to improve. He is now 1 year into this brand and has never been better. His coat is thick and shiney and his ears are near perfect(except when he sneaks a treat from the grandkids). I only wish we had done this sooner as he may not have lost his hearing. It is the only brand for a dog with Grain and Protein allergies!

Rated 4 out of 5 by cathy23 Allergic reaction resolution!
My poor Sadie has been riddled with skin afflictions for about six months now. She is constantly itching but since we started Hills she seems to be itching less and her sores are healing. The vet told me it would take about 9 weeks to see the full effect if indeed she has allergies. We are about 4 weeks in now. I will be sure to let you know.

by Mystique223 My male English Bulldog's itching has greatly improved since I have been using ZD. And whatever it has in it, it distracts fleas. His skin improved.
My English Bulldog's sensitive skin has improved so much since I started using Hills ZD for sensitive skin. The itching has stopped and the redness disappeared. He also loves the flavor so much. His digestion is also very good, so whatever it has in it, helps him in so many ways, including him not getting one flea. I appreciate that this can be shipped to me without a shipping charge as well. I have tried other products for sensitive skin, but it doesn't work like the Hills Science Diet ZD for sensitive skin!

Rated 5 out of 5 by Memory01 This works, and Jasper loves it.
My vet recommended Hill's Prescription ZD for my dog's skin allergy. Jasper loves the taste and I can see the difference in his skin after just 1 week. No more red, raw patches. Jasper is a calm dog again.

Rated 4 out of 5 by JoyPups Great for my dogs and they love it
One of my dogs got a flu-like illness about once a quarter with no apparent cause. My vet recommended this food and so far so good. She is well and loves the food which is great a she is picky. One of the best things is that my most picky eater a 16 year old cocker spaniel absolutely loves it! The first night I gave it to the one dog, my cocker did something she have never done--she went over to the other dog's bowl to steal the food. Well, it is a hit with all of my dogs and if it keeps them well it pleases me no end. The only problem is that it is unbelievably expensive.

Rated 3 out of 5 by Itchydogsmomma Food was prescribed by vet to help allergies
We are currently trying to "cleanse" our dog from meat proteins as suggested by our vet to help with her allergies. We are only about a month into it and it seems like her itching has subsided some, but is not totally gone yet. We were told to keep up with this for 3 months, so we will see if it works!

We have two Wheatons and they tend to have several allergies, some food and some yeast. We have tried so many things to control our poor pups discomforts and the Hill's Prescription Diet z/d Canine Ultra Allergen-Free Dry Dog Food was the ticket! We are so thankful and pleased!

Rated 5 out of 5 by Nyrich Provided relief from skin irritation and scratching.
The Hills dog food was effective in neutralizing the incidence of scratching, open sores my 7-year old lab/coon hound mix has experienced over the last year. I mix two tablespoons of brown rice (for fiber) with a cup and 1/4 of the dog food. She loves the food and no more health issues.

Rated 5 out of 5 by WarEagle22 Such a great product!
My 8-year-old golden retriever has had allergy problems and constantly had ear infections. One vet was content to just keep giving her steroid shots; I never liked that, and they were not only not helping much anymore, but they were hurting her hips. The new vet said he's had about a 90-95% success rate with dogs that have used this food, so we gave it a try. I had tried so many different foods, including limited ingredient ones that got great reviews, so one more couldn't hurt. She's been on the z/d food for more than 2 mos. now, and it's made such a big difference. There was a time or two I was tempted to stop it because it didn't seem to be helping, but the vet said it can take 6-8 wks. or more to really see a difference, so we hung in there, and I'm so glad we did. It has totally cleared up her ears, and they were always so bad before. If your dog has allergies, I recommend giving this food a try. It's pricey, but its formula works, and it's worth the cost. The Chewy price and service are awesome.

Rated 5 out of 5 by DobeLover Dog is Allergy Free
My two year old doberman developed severe allergies and ear infections. Vet said lets start with food, since it is the most common allergy. He also said food allergy tests are not very accurate. It worked!! Horrific hives, ear infections, etc are all gone. Of course we need to wait till summer comes and see if it holds true. Otherwise it is allergy testing for grass, etc which are very accurate, so my vet says. I have even put my 11 year old dobe on it and her tummy issues have cleared up. Plus my dogs love this food.

Rated 5 out of 5 by ELMER 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!

Rated 5 out of 5 by Dudley7414 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!

by Pookiecat2 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.

by bell96 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 Chewy.com offered the best price and super fast shipping for a great product. Doesn't get much better than this!

Rated 4 out of 5 by Jenn31 Our dog thinks it tastes great!
Our dog is having some unknown allergies and therefore my vet suggested Hill's Science Diet z/d. I thought I would have a super hard time getting my dog to eat this but quite the opposite as he is enjoying meal time with no issues. To purchase through my vet would have been a little bit more so I am happy that I found it through chewy.com. Also purchasing through chewy.com allowed me to get my other dog food at the same time which was very convenient. I have been purchasing all my dog food for several weeks now on chewy.com and I am very pleased with the service and food I have received.
