A Dog's Guide to Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food

If a domesticated dog could speak human, suffering from food allergies and urinary issues would be top of the list. Food sensitivities and adverse skin reactions can cause potentially serious problems, such as skin irritation, rashes, or even gastrointestinal upset. They can wreak havoc on a dog's comfort, overall health, and quality of life.

The good news is that there are dog food brands that prioritize nutrition, digestive care, and food allergies. Hill's clinical nutritionists formulated Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food to guarantee support for their food sensitivities and adverse skin reactions, as well as complete and balanced nutrition for your dog's needs.

When looking for the right food to continue to enjoy a happy and active life, consider Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food. Your dog will ruff, My sensitivities won't get the best of me!

Why should your dog eat Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food?

This food has clinically demonstrated visible improvement in the dog's skin and coat after 30 days. This specialized z/d recipe supports a healthy immune system, promotes a healthy skin barrier, helps normalize stool quality, and helps skin and digestive signs of adverse reactions from food.

The specified ingredient blend of highly hydrolyzed animal protein (z/d) and single purified carbohydrate source, high levels of vitamin E and natural fiber, and essentially enriched fatty acid provides the best results and safety for eaters.

Nutritional Value

Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food contains nutritional values in crude protein, fat, and fiber:

Crude Protein (14.5 %) is the measure of all sources of nitrogen and includes nonprotein nitrogen, which may have no human value. Crude protein is a chemical analysis of the protein (e.g., chicken, milk, etc.) and non-protein (e.g., grains) amounts in the food. The recipe's low crude protein is important to avoid overtaxing the kidneys.

Crude Fat (10.0 %) is the term for fat-soluble materials such as lipid content in your dog's food when ingested. The diet is restricted in fat.

Crude Fiber (6.0 %) is a measure of indigestible cellulose, pentosans, lignin, and other components of this type of chemical fibers. A highly digestible fibrous food boosts the healthy absorption of essential vitamins and minerals. It provides major intestinal tract peristalsis, a wave-like muscle contraction to relax the stomach muscles.

Daily Feeding Guide and Care Instructions

Available food bags are 7 lb., 8 lb., 17.6 lb., and 25 lbs. Bags of Original Flavor. A dog's body weight, age, and condition can affect how much your canine is given daily. See the dosage chart below with recommended daily feeding portions per cup for adult dogs:

What does Z/D stand for in dog food?

The z/d in dog food stands for Skin/Food Sensitivities. Dogs can have health problems that arise due to food sensitivities. Much of these problems have to do with their skin. These food sensitivities can lead to skin irritation, coat conditions, ear problems, as well as gastrointestinal problems. That is why experts came up with the z/d veterinary diet to deal with food allergies. These food items help support a healthy immune system while making sure that your dogโ€™s food sensitivities do not lead to any adverse skin problems. All this helps your dog lead a happy and active life, and makes sure you do not have to worry about their allergies.

What's the best dog natural food for sensitive skin?

The Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food is the best natural dog food for sensitive skin. The Hillโ€™s z/d contains important natural nutrients and ingredients like chicken liver, corn starch, cellulose, lactic acid, vitamins, calcium, and so on. It also contains important minerals like zinc. The food is infused with natural flavors too. So despite being a prescription dog food, it still provides all the natural ingredients for dealing with your dogโ€™s sensitive skin.

What is good hypoallergenic dog food?

The Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Dog Food is the best hypoallergenic dog food. It contains ingredients that tackle skin problems in dogs and makes sure they are safe from skin reactions and allergies.

Why is Hill's Z D dog food prescription?

The Hills z/d dog food is prescription-based because it deals with sensitive skin problems in dogs. Hence, the food needs to be administered in the right amounts as prescribed by the vet. Thus, it is prescription dog food.

Can any dog eat prescription dog food?

Any dog can eat prescription dog food, but they should not do so without consulting a vet. Prescription dog food is specifically made for dogs who have certain health conditions or nutritional requirements. The prescribed food is given to them to work on those conditions and requirements. While an ordinary dog can have prescription dog food, vets suggest that they should not do so unless they are specifically instructed. So you should avoid giving prescription dog food to your dog unless your vet tells you to do so. In the meantime, you can continue with regular food or even supplements (that are not prescription-based).

Why is some dog food prescription-only?

Some dog food is prescription-only because they are used to treat special or medical conditions, and need to be administered in the right amounts. There will be times when normal food for dogs will not prove to be enough to meet their nutritional requirements. In some cases, they might need additional quantities of a certain nutrient or mineral to help them recover from a health condition. That is where prescription dog food comes into play. They help provide your dog with all those things. However, they have to be administered in the right amounts and at the right times. Thus, some dog food is prescription-only, and you are allowed to use them only if a vet permits you to.

How can I get my dog to eat his prescription food?

Mix the foods. Dry dog food that comes in powdered form can be mixed with regular dog food and then given to your dog. It will be as if he were having a regular meal and will not grow suspicious. You could use some flavor enhancers to see if your dog will take it then. The chicken flavor does a pretty good job when it comes to attracting dogs. Warm the food slightly. However, this might not always work, depending on your dogโ€™s preference. Some dogs like it at room temperature while some even prefer the cold ones.

Is prescription dog food really better?

Yes, prescription dog food really is better. Sometimes, your dog needs additional nutrients for its growth and development. At other times, it needs to have a more restricted diet to ensure sound health. Prescription dog food exists to ensure all those things. Once you consult your veterinarian doctor, they will take a close look at your dog or puppy and prescribe a dietary plan accordingly. Part of that plan is sure to include prescription dog food, which is there to make sure that your dog is getting all the required nutrients and mineral content. Thanks to prescription dog food, your dog can enjoy sufficient quantities of soy protein, essential fatty acid, natural fiber, and other important nutrients. All these will help keep the dog healthy and prevent any sort of fatal health risk.

What food causes skin problems in dogs?

Individual dogs may have different sensitivities or allergies, so what affects one dog may not necessarily affect another. Certain ingredients are more likely to cause allergies in dogs, leading to skin problems. These can include common allergens like beef, chicken, dairy products, wheat, soy, and corn. Foods containing artificial additives such as food coloring, preservatives, and flavor enhancers can potentially lead to skin irritations or allergic reactions in some dogs. While not all dogs are sensitive to grains, some may develop skin problems due to grains like wheat, corn, or soy. Grain-free diets have gained popularity as a result. Surprisingly, some dogs can be sensitive or allergic to fish. Common symptoms include itchiness, redness, or rashes on the skin. Dogs can also have intolerances to certain ingredients, which may result in skin issues. These can be specific to individual dogs and may require dietary modifications to identify the problematic ingredient.

What should I feed my dog with sensitive skin?

If your dog has sensitive skin, provide a diet that promotes skin health and reduces potential irritants. Choose a high-quality dog food that uses high-quality protein sources as the main ingredient. Look for formulas with limited ingredients to minimize the chances of triggering allergies or sensitivities. Avoid foods that contain common allergens like beef, chicken, wheat, soy, and corn. Consider introducing novel protein sources that your dog hasn't been exposed to before. Examples include venison, duck, rabbit, or even exotic proteins like kangaroo or ostrich. These novel proteins can be less likely to cause allergic reactions in dogs with sensitivities. Some dogs with sensitive skin may benefit from a grain-free or hypoallergenic diet. These diets eliminate grains like wheat, corn, and soy, which are potential allergens for some dogs. Opt for grain-free formulas or specifically labeled hypoallergenic diets. Include sources of omega-3 fatty acids in your dog's diet, as they promote skin health and reduce inflammation. Fish oil supplements or foods rich in omega-3, such as salmon or flaxseed, can be beneficial for dogs with sensitive skin. Consult with your veterinarian for appropriate dosage recommendations. Consider adding fresh, natural, and whole foods to your dog's diet. This can include cooked lean meats, vegetables like carrots or green beans, and fruits like blueberries or apples. Always ensure that any added foods are safe for dogs and do not include harmful ingredients like onions, garlic, or raisins, which can be toxic to them. Pay close attention to your dog's response to the diet changes and monitor their skin condition. If the issues persist or worsen, consult with your veterinarian. They can help identify potential allergens, perform tests, and recommend a more tailored diet or prescribe hypoallergenic foods if needed.

Is rice good for dogs with sensitive stomachs?

Rice can be beneficial for dogs with sensitive stomachs, as it is easily digestible and can help soothe gastrointestinal upset. It is often used as a bland diet option when dogs experience digestive issues such as diarrhea or vomiting. When feeding rice to dogs with sensitive stomachs, use plain, cooked rice without any added seasonings or spices. Both white rice and brown rice can be used, but white rice is generally easier to digest. You can mix cooked rice with a small amount of boiled, plain chicken or lean ground turkey to make it more palatable and provide some protein.

Are eggs good for dogs with sensitive skin?

Eggs can be beneficial for dogs with sensitive skin, as they are a good source of high-quality protein and contain essential fatty acids that contribute to skin health. However, every dog is different, and while eggs are generally well-tolerated, some dogs may have individual sensitivities or allergies to eggs. If you're considering adding eggs to your dog's diet, introduce them gradually and monitor your dog's response. Start with a small amount, such as a teaspoon of cooked egg, and observe for any signs of allergic reactions or digestive upset. Signs of an allergic reaction may include itching, hives, swelling, or gastrointestinal disturbances. If your dog shows no adverse reactions, you can continue incorporating eggs into their diet. Cooked eggs are preferable to raw eggs as they reduce the risk of potential bacterial contamination. You can lightly scramble or hard-boil the eggs without any added oils, seasonings, or spices.

How can I fix my dog's sensitive skin?

Fixing a dog's sensitive skin requires a comprehensive approach that involves identifying and addressing the underlying causes. First, schedule an appointment with your veterinarian to assess your dog's skin condition. The vet can perform tests to determine the cause of the sensitivity, such as allergies, infections, or other underlying health issues. Work with your veterinarian to identify potential allergens causing your dog's skin sensitivity. This may involve allergy testing or elimination diets to pinpoint specific food or environmental triggers. If food allergies or sensitivities are suspected, your veterinarian may recommend switching to a hypoallergenic or limited-ingredient diet. This involves eliminating common allergens from your dog's food, such as beef, chicken, wheat, soy, or corn. Follow your veterinarian's guidance regarding the appropriate diet for your dog's specific needs. Establish a regular bathing routine using a mild, hypoallergenic shampoo recommended by your veterinarian. Avoid using harsh or scented products that may further irritate your dog's skin. Be sure to rinse off all shampoo residue thoroughly. Identify and minimize potential environmental allergens in your dog's living environment. This can include dust mites, pollen, certain cleaning products, or fabrics. Keep your dog's bedding clean, and consider using hypoallergenic or natural cleaning products in your home. Your veterinarian may recommend supplements such as omega-3 fatty acids or antihistamines to help improve your dog's skin health and reduce inflammation. In some cases, they may prescribe medications to manage skin allergies or infections. Regular grooming can help maintain your dog's skin health. Brushing removes loose hair, dirt, and allergens, while also stimulating the production of natural oils that protect the skin. Ensure that grooming tools are clean and suitable for your dog's coat type. Identify and avoid potential irritants that come into contact with your dog's skin, such as harsh chemicals, certain fabrics, or insecticides. Use pet-safe, hypoallergenic products whenever possible.

Our terrier did not usually want to eat and was throwing up all her food within a few hours of eating. Because of that she was always hungry and begging for treats. Our vet recommended z/d dry food and from the day she started on it, no more vomiting. She was eating all her food too! We went through 2 bags thinking our problems were finally solved! The last bag we purchased, I noticed the color had changed from dark brown to a mixture of dark brown / light brown. She won't touch it so now we're back to square one. What's going on? Obviously you've changed the ingredients without any info on the bag that we know of.

15 years without a problem

Our sweet westie Cesar was on ZD forc15 years. He was diagnosed with allergies at age 2 by our former vet. She recommended ZD and he was on it until he crossed rainbow Bridge almost 3 weeks ago. I would highly recommend this product to any pet parent of a westie who has allergies.

I spoke to my vet as to why the corn starch and she replied

This food works for my Australian shepard mix who has allergies and no thyroid and has to be supplemented. She doesn't chew on her feet and scratch anymore. After reading other's comments on the corn starch I asked my niece who is a vet. The corn starch provides protein that can be broken down into strands that don't promote allergies. The corn also provides lysine and that's great for the skin. Z/D is certified by AAFCO standards which means it is balanced. I'm glad I asked so that I have more information, as corn gets a bad rap I think. After 6 years of trying to figure out what's wrong with my dog, I now know what's right and this works.

Changed our lives!

My dog suffered allergies for her entire life. We tried diets and shots. When my regular vet was out with Covid a retired vet filled in for him. When I took her for her monthly shot, which really was not very effective, the retired vet suggested we try this dog food. It has been a real game changer, her allergies are controlled now way better than the shots or any other food ever worked. And itโ€™s actually cheaper than the monthly shot!

Why the shortage of large bags?

This is not a whole food and it is kibble to boot. Have a small bag and it's temporary feeding only. Love my pup way too much to feed her this garbage for too long. Not good enough and from Hills Prescription no less.

Fattening up with Corn Starch

This is the only dog food my golden retriever can eat without getting upset stomachs or skin irritation. However the first ingredient is corn starch and I don't think feeding my dog a high concentrated form of corn starch is healthy for my dog. I feed him the recommended feeding guide for a 35kg adult dog, however my dog gained 10kg! And is now overweight. Even with regular min 1 hr exercise every day. He doesn't get treats everyday unless it's carrots. I have a feeling this made him fat. Though it helped with his allergies, it just caused another problem to worry about.

Trial & Error (lots of error)

I have read many of the comments. I agree with the upsetting fact that Corn Starch is the first ingredient. I have a Bichon with major skin & belly allergies. He is allergice to everything (no exaggeration). Recently we adopted a Cavi-chon. She was eating a Rachel Rey food, so I mixed both to ease her in & give my Bichon a treat. The Bichon's poops were always watery and seemed lesser than a normal poo. Well, 4 weeks later... both are scratching & rubbing & Bichon is shaking his head w/ red, red ears. Their poops are much better, formed & firm, but they are both miserable. So, donating a big bag of RR food & back to ZD! Will supplement with bone broth & psyllium husk to improve poo production, I guess. Thanks for developing a food that works for doggos that are allergic to just about everything. We are customers for life!

My yorkshire terrier vomits lots of mornings (from it's firsth age). My dog has been treated for stomach via some drugs and Hills I/D. There was not result. In this case We tried D/D according to Our vet suggestion. Than We started Z/D. My yorkshire terrier is better . I have to say that big size grain was big problem for my little yorky. I had to grinder original size Z/D via kitchen robot, in this case each part was abrasive for sensitive stomach surface. This was new problem for us. My yorky started to recover WITH SMALL ORIGINAL SIZE Z/D. SMALL ORIGINAL SIZE IS ACCEPTABLE FOR MY LITTLE YORKY. I food My yorky with Hills Z/D from 3 years. And we will continiou with Z/D. Our healt problem is not finished completely but solved with Z/D at big value . PRESCRIPTION FOODS may be required for any kind & any size of dog. Big dog can eat little size food but small dogs can NEVER bite big size (grain is already very hard.)

It's the only thing she can have

I was told when I adopted her from the local humane society, this was all she could eat. I didn't believe them. It took me a long time of trial and much error to realize they were right. It's ALL she can eat. I've tried other holistic, expensive brands. Even big brands like Wellness and Blue Wilderness. Z/D is the only thing she can eat. I have the vet bills to prove it. She wolfs it down so I assume she likes it. Then again, she tries to eat anything and everything so that doesn't really mean anything. It smells terrible. But I have no complaints from the dog. It's ridiculously expensive and it kills my budget. But I'm stuck. It's the only thing she can eat!

Fixed the allergy problem

I started my English bulldog on the z/d after the vet recommended it. We were battling severe skin allergies, licking his red swollen paws, ear infections, diarrhea, runny nose, eye infections. Basically everything. He was miserable. We're a year out from when we started the z/d diet and we no longer have to do the allergy shot, any allergy meds, and haven't had any infections. The only downfall is it is pricey. We started our 2nd English bulldog on it as soon as we switched her to adult food in hopes that we can prevent the allergy problem.

Finally some relief!

My Yorkie Lhasa Apso mix was so stinky and so itchy that he would have to get steroid shots to help with this discomfort. After using this food for 3 or so weeks, the smell was practically gone and his itching had stopped. I will be starting my second bag today. The food smells and, I think, tastes very good. The other three dogs that I have want to eat my Yorkie food.

Works Great!

My vet recommended this product for both of my dogs itchy and scratchiness. I was hesitant because any other quality food I've tried to give them they refuse to eat. I got a small bag and mixed half and half, came back a little later to see all of the new kibble gone and pieces of the old kibble around the floor where they spit it out. I was shocked that they loved it more than their current kibble. Bruno, who has the most itchy, scratchy problems, has seemed to improve, but we haven't been on the new food for very long. Will definitely recommend!

So far so good!

I've always given my 11 year old papillon Hills products and have good luck! In his old age my vet sugggested this and he seems to like the taste and I'm hoping it helps with the itching.

The only food for my lemon!

I struggled for 2 years trying to put weight on my dog, he was eating me out of house and home just to maintain a normal body condition. After surgery the vet prescribed the ZD formula and now my 85 lb GSD only eats 2 cups a day & is a beautiful BCS! Thanks for the wonderful product he will be on it for the rest of his life.

A miracle for keeping my Pip healthy

On any other food my Pip has horribly mucus diarrhea. He endured medical test after test trying to diagnose why. Just before we were going to do a surgical biopsy on his small intestine (he was only 5 months old!) we decided to do a trial of Z/D. It was miraculous! Yes, it's expensive but better than vet bills and an unhappy dog with diarrhea. Pip is now 7 years old, happy and has beautiful poo...as long as no one at a dog park feeds him treats!

Finally, relief for my dog!

Simon stopped shedding, scratching, and being a stinky boy within about 2 1/2 weeks of switching to z/d. He's also playing like a pup again!

Not Helping

My 4 year old pit bull is allergic to everything and this food did not help her at all. She likes the taste but she is still scratching after she eats it.

Our vet recommended this for our 9 year old Yorkie who has become sensitive to her previous foods. Not only does she like but it has cleared up the itching and scratching.

Surprised & Confused!

My 3.2 lb yorkie has had stomach issues for about a month. Diarrhea mostly & some vomiting. It occurred to me that the zd dry food we have feed her for the past 10 years has changed sizes 2x during the past couple months. It went from the larger chunk(apps.1/4 inch sq.) to a flat circle to a mini tiny chunk. Is this all the same ingredients? Has the formula changed? Even though we were happily surprised with the size change, our yorkie has had intestinal problems since the change. Can I get some info or advice? Thank you!
