Hill's Prescription Diet z/d Canine Ultra Dry Dog Food 4.7 5 81 81
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! July 28, 2014
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. July 18, 2014
Very convenient to order the product on line. Reliable company, it certainly allows you the convenience of ordering a large quantity of food without the burden of carrying it oneself. January 14, 2014
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. June 16, 2014
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. March 9, 2014
Really upset Ella's bowels My doctor recommended this product for my pitbull Ella for her allergy condition. Since she's been on it, her stools have been erratic and one step away from being diarrheal. She seems to have lost weight and is hungry all the time. To be honest, she has also been on medication which might have something to do with it, but she's been on the same medication before without any problem. Will have to see what the doc says at her next appointment. December 13, 2013
Excellent aid for allergies. Good product and great help with dog allergies. Wish it weren't so expensive. July 24, 2014
My Doberman Loves the Taste! My doberman seems to be allergic to everything. She will break out in bumps and at times hives. Then she gets skin staph infections. This food has greatly reduced the bumps to just a few. I am also controlling staph with medicated chlorhexidine shampoos. I tried Royal Canins hydrolyzed formula and she refuses to eat it. Canins is soy based protein and Hills is Chicken. Glad to have a food she can eat. However is is very expensive. $100 a month for dog food! January 24, 2015
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! January 12, 2015
Excellent Easy transaction & great customer service. Their products come right to your door. How much easier can it get! This product greatly helps if your pet has allergies. January 10, 2015
Worth it! Sticker price for prescription food was a bit overwhelming but the overall effect has been better than we hoped. Our dog loves this food and is more eager than ever to eat now. He has had several symptoms going on and all of them are getting much better now! January 10, 2015
Good food, but does it work? The jury is still out as to whether or not this food is helping my dogs with their allergies. We are on day 5 of Hill's Prescription Diet and my dogs continue to scratch and chew themselves. They also receive allergy serum injections once-a-month and I'm overly cautious about whatever goes in their mouths or on their bodies. It's very frustrating. They love the food and gobble it right down. I also purchased the dog biscuits, which I cut into 4 pieces so they only get small bites for treats. Of course, those are a big hit as well. I'm unsure how long we need to wait to see if the food helps. I'll post an update later. January 7, 2015
Great food recommended by my Vet. I am thrilled to hVe discovered Chewy.com. Extremely fast and courteous service, and discounted prices. I signed up for auto ship. No more trips to the vet and schlepping home 25 pind bags of food. Savings to boot! January 6, 2015
Happydogsx3 I have three dogs all with food allergies. We have tried every food there is with constant GI issues. The potato and venison Royal Canin was the only food they all tolerated with no problems. They have been on it for several years now. It is prescription and the price from the veterinarian was reaching over $100/bag for 25lbs. Tried another brands version but it resulted in more GI issues. Thought I was going to have to pay the high price until I discovered it thru Chewy.com. It is $25/bag less which makes it affordable and I have happy dogs! January 6, 2015
This product is good for dogs with kidney or liver problems My dog likes this food. I do think that is it too expensive and should be at a more affordable price. January 5, 2015
The product is excellent. With free shipping, your price is competitive with what my veterinarian charges. And delivery was prompt. The product is excellent. Your price was competitive. And delivery was prompt. January 4, 2015
THE PRODUCT IS AWESOME FOR MY TOY YORKIE I LOVE THE FOOD FOR MY DOG. I HAVE A TOY YORKIE AND THE FOOD IS GREAT. SHE NEVER GETS AN UPSET STOMACHE WITH THIS FOOD. I AM VERY HAPPY AND PLEASED. NO COMPLAINS THIS WAY. I WOULD RECOMMEND THIS TO ANYONE. December 30, 2014
Really good option for dogs with allergies This is the third dog food we have tried with our dog. We have a three year old Labrador mix rescue who we adore. Roscoe has been such a joy however we have been challenged by his inability to keep his food down, itchy skin on his face and feet. He was on Science Diet when we first got him then we switched him to Call of the Wild which he has been on for 1 1/2 years. His symptoms are better but he still would throw up his food once a week and scratch his face periodically. We switched him to Hill's Prescriptions Diet and over the last month he has only thrown up one time. We are going to keep him on it for 12 weeks and beyond if he continues to do well. December 29, 2014
great for my dog who has allergies she loves it!! wish it came in smaller bites though as my dog is an elder chihuahua. I have to soak her food first. December 23, 2014
Great dog food My dog used this food 5 years ago for allergies. Everything about him improved. Decreased scratching, gorgeous hair and nails, happier. I wish I could have continued using this forever but the price increase of $30 inhibited this. Now we have to try it again as it will hopefully decreased his need for allergy meds and therefore balance out the cost. This was the best dog food ever and hopefully will work this way again. . December 19, 2014
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! December 19, 2014
Happy to get Z/D Ultra at a good price First time I have used Chewy.com to order a product. They had the best price I could find and a fast delivery. Will buy again. December 19, 2014
mixed food with his previous food for about 1 week...minor stomach upset with the change of the food...but noticed my labs ears are better already! my labs ears are already improving...my dog loves the new food! December 17, 2014
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! December 9, 2014
Excellent customer service I was at a loss when my vet had a fire and wasn't open. Chewy helped me get the food I needed without any hassle. Great customer service. Food arrive as scheduled. November 29, 2014
PAT'S ENERGY LEVEL IS IMPROVED, BUT STUHL IS STILL PROBLEMATIC. Our 12 year old golden seems more alert. Her digestive tract is obviously improved, but her droppings vary between soft and very soft. She has only been on Hills ZD for 2 weeks. Being 12, she maintains her weight on less than the recommended quantity of food. She weighs 74 lbs and we have been feeding only 3 cups daily. November 25, 2014
My dogs love this food While expensive, this food may be what solves my Rottweiler's constant ear infections. After 90 days so far so good. My dogs were grazers before and never ate their food right away. Not now - they eat it immediately. It smells like a pot roast for dogs. Size of dry crunchies is good. What I don't understand is the need for a prescription for purchase. Chewy delivers quick and makes it easy to obtain. November 25, 2014
excellent I got to your website from Hills web site. I've been very pleased. Britney even gave me a web site for some medication you don't carry where I can get a good price, which for me was above duty. November 13, 2014
No other choice for my dog's allergies! This food has chicken as protien and supposedly its hydrolyzed so small it cant cause allergic reaction. My dog had allergy testing and is allergic to chicken and tons of other ingredients in dog foods. I searched for a dry food and could not find a beef, fish, rabbit, or turkey dry food without other foods he can't have in it. Not even a dehydrated or raw food. So we are trying this food. It is expensive!!!! My vet wanted more for it, so I order it here. Just had to have Chewy call my vet for prescription approval. My dog's allergies got so bad before allergy testing that he got a hemotoma on his left ear from head shaking and dirty ears. He hated the cone he wore while his ear drained. October 24, 2014
