Have you noticed that your dog is suffering from recurring ear infections or yeast infections? Does your dog seem to be excessively biting to scratching their skin, ears, or paws? Do they have a sensitive stomach or suffer from bloating, gas, vomiting, or diarrhea?

If you answered yes to any of these questions, your dog may be suffering from allergies. Allergies in dogs are often caused by an ingredient in their food, so trying a new food may help eliminate the cause of their allergies. Before trying new food, it is important to consult with your veterinarian if you think your dog is suffering from allergies. They can help you identify the cause of the allergies, so you can eliminate the right food(s) from your dog’s diet.

In most cases, veterinarians will recommend a limited ingredient diet with allergies. These diets include fewer ingredients, which can help you pinpoint the specific ingredient that is causing your dog such troubles.

If a limited ingredient diet is effective, a veterinarian may recommend switching to hypoallergenic dog food. Hypoallergenic foods are formulated with chemically split, or hydrolyzed proteins. This process prevents the allergen from irritating a dog’s immune system. In many cases, a veterinarian will need to prescribe hypoallergenic dog food, but there are a few that can be purchased online as well.

In the next few sections, we’ll outline our picks for the top foods for dogs suffering from allergies. Use our recommendations, along with the information your veterinarian shared, to help you find the right food that will ease your canine companion’s suffering and increase their comfort and happiness levels!

How to Determine What is Causing a Dog’s Allergies

Determining that your dog is suffering from food allergies is the first step. Figuring out what is causing their allergies is next and can take some time and effort. Many veterinarians recommend using an elimination diet to find out what is causing a dog’s allergies.

With an elimination diet, the first step is to stop feeding your dogs all the foods they currently are eating. Then, you’ll want to feed them a very basic diet by eating new food. Give the dog’s allergic symptoms from the old allergy time to clear up, then you can slowly start to reintroduce the old foods they were eating that may be responsible for the allergy.

If you notice a reaction to one of these foods, it will let you know that this was the cause of your dog’s allergies, and you should avoid giving them any foods with that ingredient.

While dogs could potentially be allergic to any ingredient in their food, some of the most common allergens for dogs include:

Food Allergies vs Food Intolerances

Oftentimes, food intolerances are mistaken for food allergies. While the two conditions can share some symptoms, they are not the same thing.

Food allergies are the result of a dog’s immune system acting as if an ingredient is dangerous. The immune system creates antibodies to fight off and protect itself against this danger. This can manifest itself in a variety of ways including itchy or sensitive skin, ear infections, yeast infections, red or irritated eyes, a sensitive stomach, or digestive issues.

Food intolerances, on the other hand, are the result of digestive problems. The dog is unable to properly digest an ingredient in the food, which can cause bloating, constipation, vomiting, or diarrhea.

Best Dog Food for Allergies: Reviewed for 2021 FAQs (Frequently Asked Questions) 

What is the best food to give dogs with allergies?

The best food to give your dog with allergies will depend on the specific foods he or she is allergic to. Since dogs can be allergic to many different foods, the first thing you should do is to work with your veterinarian to identify the ingredient or ingredients causing your dog’s allergies. Then you can choose a dog food that is made without this ingredient.

Does grain free dog food help with skin allergies?

Grain-free food can help with skin allergies for dogs caused by corn, wheat, or other grains. Some veterinarians will recommend switching to a grain-free diet to see if it is effective when a dog develops skin allergies.

What ingredient in dog food causes allergies?

Every dog is different and could potentially be allergic to any ingredients in their food. However, there are a few ingredients that are more likely to cause a reaction than others. These include wheat, corn, beef, chicken, egg, soy, lamb, pork, rabbit, and fish.

What foods to avoid for dogs with allergies?

Working with your veterinarian to identify the specific food that is causing your dog’s allergies can help you know which foods you should avoid. Some of the more common allergens for dogs include chicken, beef, dairy, eggs, wheat, corn, lamb, soy, pork, fish, and rabbit.

How can I help my dog with allergies?

If you think your dog is suffering from allergies, overall, the best thing you can do is to schedule an appointment with his or her veterinarian. They can help you determine whether the allergies are being caused by food or something else. If they believe their allergies are food-related, your veterinarian can work with you to determine what is causing your dog’s allergies.

In many cases, they may recommend using an elimination diet. For this diet type, you’d switch to a new food that uses a different protein than what was in your original food. This may help you determine if the protein, such as chicken, in your dog’s diet was the cause of the allergies.

Your veterinarian can work with you to eliminate other potential allergens from your dog’s diet until you determine which one is the culprit for their allergies.

What are some of the main symptoms of food allergies in dogs?

There are many different ways food allergies can manifest themselves in dogs. These include infections, such as ear infections and yeast infections, sensitive skin and itching, patchy coats, irritated eyes, diarrhea, vomiting, and gas.

What is the difference between a food allergy and a food intolerance?

With food intolerance, dogs may suffer digestive issues or a sensitive stomach. Food allergies, on the other hand, can be more serious. Food allergies can also cause a sensitive stomach, but since they are tied to the immune system, they may also cause a dog to wheeze, cough, or even go into anaphylactic shock.

What are the benefits of a hypoallergenic diet for my dog?

A hypoallergenic diet may be recommended for dogs that are allergic to multiple ingredients. Dogs that are suffering from allergies, can experience relief in their symptoms. Their skin will feel less itchy, their stomach won’t bother them as much, and they won’t be in danger of suffering from anaphylactic shock, which could potentially kill them. Switching from foods that are causing your dog allergies will not only make him more comfortable but can also help him live a longer and healthier life.

What is an elimination diet?

An elimination diet is used to help identify the cause of a dog’s allergies. To start an elimination diet, you should take away all the different types of food your dog was preciously eating and only feed him base ingredients for a few days. Then, you can gradually introduce new foods. After the introduction of each new food, look to see if they are causing an allergic reaction. This will tell you that the new food is causing your dog’s allergies.
