This article will provide you with the essential information needed to understand food allergies in dogs and what you can do as their owner to help them. From there, we will go over foods for dogs with allergies tips to follow as you care for a dog with these problems. Even though it may take a few trial runs to find the best food for your pet, once you do, he will go back to his normal, happy self in no time at all.

What Causes Dog Food Allergies?

Although there are many causes of food allergies, most pet care professionals believe having a predisposition to allergies is a major factor. However, all dogs at any age can develop allergies. It is also not uncommon for a dog with food allergies to develop other sensitivities to environmental factors or airborne allergens as well. In most cases, dogs develop these allergies from a reaction to certain types of protein. When a dog suffers from these allergies, their body mistakes these protein molecules as a potential threat.

A dog could be eating the same food for their entire life and still develop an allergy at some point down the road. That is because allergies take a while to develop, and can come on at any point in an animal’s life. As a general rule of thumb, the most common culprits that cause these allergies to occur include wheat, beef, chicken, and dairy.

What are the Common Signs of Food Allergies in Dogs?foods for dogs with allergies

Most owners of dogs with allergies report a generalized itchiness and head shaking as the main symptoms. These two symptoms are the most common signs to look out for. Another common symptom is recurring ear infections. Whether your dog is a swimmer or not, frequent ear problems is never a good sign. If he has more than 2-3 ear infections a year, that could mean he is suffering from a food allergy or other internal health complication.  

Another lesser-common sign of food allergies in dogs is the color of their nail bed. If the upper part of your dog’s nails is brown or bronze, that could mean they have an underlying health issue linked to their food intake. This is easily detectable if your dog has white fur. You can also check the area around their mouth for any discoloration as well.

The last most important sign of food allergies is a reduced coat health. Does your dog’s coat look dull and brittle? If his coat is dry, red, or flaky, that is a good indication that he has some type of underlying allergy. In some cases, a dog’s itchiness can even cause hair loss. Keep an eye on your dog’s coat health. These changes are not typical of a healthy dog and should be checked by a professional if the problem persists.

Other symptoms that can also occur include gas, diarrhea, coughing, obsessive licking, skin infections, vomiting, paw biting, hives, and inflamed feet. If any of these symptoms have been identified in your dog, schedule an appointment with your veterinarian. The sooner you can get him looked at, the faster he will be able to seek treatment.

What Are the Different Types?

Although it may be difficult to spot the difference, food allergies and food intolerances are two entirely different issues. However, they both show very similar symptoms, which means it can be hard to decipher the difference between the two.

When a dog has a food allergy, their body’s immune system is responding to an unknown threat. In this case, a dog’s body mistakes an ingredient in their diet for an unknown invader. The body has also been previously exposed to this allergen, giving the body time to develop antibodies. Most food allergies will be accompanied by the symptoms that were listed in the above section.

A food intolerance does not have any immune system reactions involved. With that being said, they can have very similar digestive issues like a food allergy. Dogs with food intolerance are unable to properly digest and break down a particular ingredient in their diet. Lactose intolerance is also prevalent in canines and will show the same symptoms as any other food intolerance or allergy.

Common Ingredients that Cause a Food Allergy in Dogs

As said before, protein sources are what causes a food allergy to occur. In a normal, healthy dog, their body will break down the ingested food and turn it into amino acids, which can later be absorbed by white blood cells. If a dog’s digestive system has a difficult time breaking down protein, their body will mistake these particles as intruders. Over time, this attacking response will grow and cause further symptoms to occur. Technically all food ingredients can cause an allergy to occur, however the most common are as followed:

  • Chicken
  • Beef
  • Dairy products
  • Lamb
  • Soy
  • Wheat
  • Eggs
  • Corn
  • Fish

How to Diagnose a Food Allergy in Dogs

Once your dog begins exhibiting any of these symptoms, take them to the vet for further analysis. From there, it is imperative that you provide your vet a list of all prior symptoms leading up to this point. Once your vet has gathered all necessary information, he will then start off by taking a skin scraping of an infected area. If their skin sample comes back negative for mites, skin diseases, or yeast infections, your vet will then assume your dog’s issue is caused by a food allergy.

Once a food allergy is believed to be the issue, the vet will recommend an elimination diet. This type of diet works to eliminate commercial dog food to identify the harmful ingredient in a dog’s diet. You can also feed your dog a bland human food diet that consists of a boiled protein like chicken and a simple carb. When you are doing an elimination diet for your dog, try to avoid all ingredients that are found in the old diet. If a specific allergen causes the dog’s reactions, their symptoms should clear up as soon as that ingredient has been eliminated from their diet.

Keep in mind that it is imperative for your dog only to consume his new diet, especially during the testing period. Although it may be difficult, make sure he is not consuming any table scraps, flavored toothpaste, treats, or flavored medications. All these sources can cause your dog to become re-exposed to the allergen, resulting in an inconclusive testing period.

If your dog is experiencing excessive itching, he may need antibiotics or antihistamines to be alleviated of his symptoms. Keep in mind however that this can interfere with the elimination diet and hide any signs that may have otherwise occurred if the dog was not on any medications. Most veterinarians will recommend providing the dog with these antihistamines after the elimination diet process i
