Important Features to Consider to Find the Best Dog Food for Dogs With Allergies
Choosing the right and best dog food for dogs with allergies can be challenging if you don’t understand the mechanism behind the development of such conditions.
Unfortunately, many dog food manufacturers do not understand the unique pathophysiology of food allergies, so they continue to produce dog food products with high allergenic potential.
You should focus more on looking for a dog food that has the least potential to cause an allergic reaction in your dog. Here’s how to choose the best dog food for skin allergies:
- Limited ingredients: the fewer ingredients in your dog’s food, the less likely you are to have an allergic reaction. The sad reality of dogs who are allergic or sensitive to food, you may never know exactly what caused his allergic reaction. To make your life easier, instead of using expensive tests and prescription drugs from the start, you can start by trying foods with a limited number of ingredients that don’t contain unnecessary foods.
- New proteins: New proteins are less common protein sources in dog food, and therefore there is a lower risk of allergies. New proteins include bison, lamb, rabbit, game, and herring.
- Grain-Free: While some domestic dogs have adapted to a more modern diet, grains are still more difficult for their bodies to digest than the meat and vegetables they would be fed without a human parent. Grain-free dog food may be just what he needs to make it. Making sure he gets the food he needs while also avoiding the added strain on his digestive system.
- No Dairy Products: Most dogs cannot tolerate dairy, and many can develop allergies. It’s best to avoid dairy.
- Raw food: it is the closest thing to your dog’s biologically preferred diet. It may seem gross, but the truth is, manufacturers can preserve the food, so you give your dog the food his body craves. That’s what helps him digest and prevent allergic reactions, all the better.
There is a huge variety of dog foods to choose from, and they all have different ingredients. Keep trying new ingredients s, and you will find one that your dog likes and won’t cause any allergy symptoms.
Now let’s move onto our list of the best dog food for allergies

This dog food is great. Our dog had extremely sensitive skin and would react (turn red, itch and lose hair) to just about anything (grass, carpet, new shampoo, flea treatments, etc.) We tried different dog food brands and eventually Purina Pro for Sensitive skin and stomach. The difference is great, all his hair has grown back, he no longer turns red and starts to itch when he is in a new environment. At the age of 6 we didn't think he would even get 7. At the age of 7 he is almost a puppy again. Thank you Purina!
This food consists of a few ingredients, which means that it contains no hidden allergens. The idea of the food is similar to what your dog could get in the wild.
The only source of meat protein in this dog food is turkey and turkey flour. The turkey was raised on the farm.
This gives the food a crude protein of 31%, which is really high for any type of dog food. There are also chickpeas in this food that also add some good protein to the food.
Because chicken is actually a general dog allergen, you never see chicken or chicken by-products in this food.
The carbohydrates in the Zignature food come from dried beet pulp and linseed. This means that there are very few carbohydrates in this food. Because carbohydrates are a major cause of allergies, it would make sense that this food does not have much.
Turkey is lean meat, so most fats in this food come from sunflower oil. It is full of Omega 6 and Omega 3 fatty acids.
Although there are not many ingredients in this food, there are still many great nutrients. The vitamin A and vitamin C in this food come from alfalfa flour.
This includes calcium, phosphorus, and crude fiber. In fact, there is 6% crude fiber in this food. The flavors of the food are also natural, derived from bone broth.
- One protein source
- Limited ingredients
- Made with farm-raised turkey
- We didn’t find any!

My dog has yeast issues and I have to rotate his dog food every 9 months or so. The vet suggested the rotation and it really makes a difference. This one is especially good because it has no grains and is low in starch. Most people look for dog food without grains, but the food still has too much starch (potatoes, rice, tapioca). The starch helps promote yeast in their systems. I would recommend this one. We are on our second bag and will have to rotate to another type of food in a few months, but this is ...
View On AmazonTaste of the Wild is a well-known international dog food brand. Although they do not have THE largest assortment of puppy food we have ever encountered in our research, Taste of the Wild still offers us a lot of choices.

Taste of the Wild first appeared just over ten years ago in 2007, and all the dry puppy food and dog food are made without grains.
They are strongly focused on using only natural ingredients and have real animal protein at the top of their ingredient list.

With premium ingredients with added vitamins and minerals, fruits and vegetables packed with antioxidants, and a fatty acid blend for skin and fur health, this grain-free dog food is both nutritious and highly digestible.
It is rich in protein for strong, lean muscles and has an optimal amino acid profile to support your dog’s health. Plus, with real salmon as the # 1 ingredient, dogs love the rich, wild taste.
- At the 25% protein mark, it’s developed to keep those strong muscles in shape.
- With no eggs, beef, or chicken, it’s one pretty good option for dogs who need to avoid certain inclusions.
- It’s full of healthy fiber and nutritious vitamins, both from garden vegetables and superfood fruits.
- It contains all the mineral supplements that your dog needs to stay happy, healthy, and in great shape (along with those fruit and veg!).

I received a bag of 15 # TOTW Pacific stream formula in early 11/2016. My 4 year old, 63 # border collie is a picky eater of dog food. It is hard to make him eat 1 / 2c of a different TOTW dog food every day. He absolutely loves this formula. His fur and skin were dry and had no shine.

View On AmazonNatural Balance Limited Ingredient Diet consists of relatively few ingredients, which is an important characteristic of allergy-friendly dog food.
In addition, this food with limited ingredients contains no artificial flavors, colors, or preservatives, further reducing the risk of allergies to your pet.

- Many owners report that their dogs digest this food better than many similar products, and some have even remarked that the food reduced the amount of gas from which their dog suffered. Additionally, the kibble is reportedly designed to encourage your dog (particularly if it is a large breed) to chew thoroughly, which can help aid the digestive process.
- Like some other hypoallergenic dog foods, Natural Balance Limited Ingredient Diet is a little pricier than regular dog foods ($49.49 for a 28-pound bag), but it is quite reasonable when compared to other hypoallergenic foods.

This stuff is THE food for our Great Dane.It contains the right amount of protein/fat ratio's needed for our fast-growing beast dog. Very healthy & high quality. It's expensive, but definitely worth the investment. We were originally using a different flavor & I wanted to switch to a more bland one or grain-free food & I found this one. Also, the kibbles are double the size of the normal kibbles which really slows down our dogs eating habits! Anyone with a Dane or dog the wolfs down his food & can get bloat... or just get sick... will love the ...

Maggie, our 10 year-old black lab, has always had a sensitive stomach. Most of her poops have been runny and very smelly. It was not unusual for her to vomit at least once a week. She can not eat any dog food with chicken in it- her BM’s would 10x worse! I hesitated to order Diamond Care (Sensitive Stomach) as it seemed all about puppies but I didn’t know what else to do. Maggie loves the flavor and immediately ate it out of my hand. It’s only been a 3 days but so far no runny poops, no smell ...
View On AmazonHill’s Science Diet specially formulated their recipe for large breeds to meet every need that a large dog will have. It is made from high-quality chicken that gives them not only an optimal protein source but also an excellent fat source that gives them lean muscles.
Some of the high-quality ingredients used contain natural sources of glucosamine and chondroitin, which is essential to help your large dog have ideal joint and bone health to support their massive bodies.
All ingredients are easy to digest and certainly offer a high-quality food source that your large dog can benefit from inside and out.

- Contains 24.7% protein
- 15% of fat
- Chicken is the first ingredient
Large breed dogs such as the Cane Corso need a scientific diet that supports the health of their body so that they can stay active for longer.

- Ideal for adult dogs over a year old
- Contains wheat and corn as the first few ingredients, which risks them being used mainly as filler ingredients

View On AmazonThis recipe uses a single source called protein: lamb, and only lamb. There is no other source of animal protein. This dog food should be one of the best dog foods for skin allergies due to this single source.
The protein from one source is also considered hypoallergenic. Admittedly, the plants used, such as linseed and peas, also have a vegetable protein content, which should slightly increase the protein content.
Wheat, corn, and soy are known to cause allergic reactions in dogs. These ingredients also contain fibers that help with the digestive process and keep the dog regularly.
Chicken fat contains linoleic acid that is rich in omega-6 fatty acids, while linseed is rich in omega-3 fatty acids. Both are considered essential for optimum nutritional health.
The chicken fat is preserved with mixed tocopherols that are not considered harmful to a dog or that are likely to cause an allergic reaction.
Vitamins and minerals are well represented in this recipe. Vitamins include A, B12, C, D, and E. Minerals present are zinc, iron, copper, manganese, and potassium.
The minerals are sequestered to limit deterioration and make them more digestible for the dog’s digestive tract.
Beet pulp is one of those controversial ingredients with two clearly opposing camps. However, most experts agree that beet pulp in the amounts present here is very acceptable as an ingredient for hypoallergenic dog food.
- Single source, named, hypoallergenic protein
- Live micro-organisms
- Chelated minerals
- No wheat, corn, or soy
- Added fruit and vegetables
- Ingredients are natural, not organic or non-GMO

We have a long haired German shepherd. I use to feed him taste of the wild ($60) when he was a pup, but I couldn't afford it after he was two.

an allergic reaction to flea saliva is the most common cause of contact dermatitis in dogs. There are various methods for eliminating fleas, from dusting with flea powder to the use of spot-on chemical deterrents.

The allergy can manifest itself as vomiting or diarrhea, or it can manifest as itchy dry skin and loss of fur. Whatever the manifestation is, you know that your dog is not happy. If that is the case, finding the best dog food for allergies.
How can I help my dog with allergies?
The first step to help your dog with allergies is to consult a veterinarian. Only a professional can check whether your dog’s symptoms are really caused by food. Once you are sure that it is a food allergy, you must identify the allergen.
Veterinarians often recommend an elimination diet to help you determine which ingredients cause your dog’s allergies.
An elimination diet means that you switch to a food with a different protein source and carbohydrate source than before – for example, you can switch from chicken and rice to lamb and sweet potato. If you notice that your dog responds better, you definitely make the switch to chicken-free dog food.
Switching to hypoallergenic dog food is a reliable way to find your dog’s food allergy.
Hypoallergenic dog food is made with new proteins and carbohydrates (that your dog has never had), such as a game and potato or duck and pea. Your dog must eat hypoallergenic dog food for at least 8-10 weeks to notice any change.
