What to Look For In the Best Dog Food for Allergies

Like humans, dogs can develop allergies to numerous things, including food! To identify the best dog food for dogs with food allergies, you must first understand what food allergies are and what causes them.

In contrast, food “intolerance” does not affect the immune system and can happen with the first exposure to a particular food. However, both reactions have similar signs and may be hard to tell apart without veterinary advice.

Reasons for Allergies in Dogs

If your dog suffers from allergies, it can make them miserable! Just like humans, dogs can have allergic reactions to various things, from environmental allergens like pollen, dust, mold, or grass to food allergens. Unfortunately, it can be challenging to determine which allergens your dog is reacting to.

Your vet can offer suggestions on ruling out common allergens to get to the bottom of your dog’s allergies.

If you and your vet conclude it is a food-based allergy causing your dog to suffer, the best treatment is to eradicate the ingredients causing the allergy from your dog’s diet.

Signs of Allergies in Dogs

If your dog is suffering from allergies, it may be showing some of the following symptoms:

  • Chronic ear infections
  • Scabs or rashes on the skin
  • Red, inflamed skin
  • Sneezing
  • Itching
  • Gastrointestinal problems (diarrhea, vomiting, excess gas)

How is a Food Allergy Analyzed in Dogs?

A food trial using hypoallergenic dog food is the only reliable way to diagnose dog food allergies. Hydrolyzed protein or a novel protein source are two ways to do this.

A “novel” protein source is relatively new to the dog, lessening the chance of an immune reaction. Moreover, the diet should include a novel, single source of carbohydrates because plants also contain protein.

Hypoallergenic dog food choices include potato and venison, duck and pea, salmon, or even kangaroo, as long as the dog hasn’t been exposed to these components.

Lamb used to be believed to be hypoallergenic but is now in so many commercial dog foods that it is no longer novel.

Hydrolyzed diets are made when complete animal proteins are broken down into tiny molecules that the immune system should not be capable of recognizing as allergens, effectively eradicating the case of an adverse food reaction. Starch or rice are generally used as carbohydrate sources as they are rarely associated with allergic responses.

It doesn’t matter what kind of hypoallergenic dog food is utilized must be fed for a minimum of 8-10 weeks to evaluate the dog’s response satisfactorily.

Most dogs experience partial progress in their food allergy signs within the first 4-6 weeks. Still, several dog breeds (including Cocker Spaniels and Labrador Retrievers) may need a more extended response period.

Feeding only hypoallergenic dog food is essential, and avoiding other treats, nutrition, and even flavored medications like chewable heartworm preventives, antibiotics, and pain relievers.

Once the food allergy has been analyzed using hypoallergenic dog food, a challenge must be conducted to confirm the diagnosis. The signs should return within two weeks when the actual diet is fed.

Following confirmation of the food allergy, single-source ingredients (e.g., slices of chicken or a sprinkling of wheat) may be added to the hypoallergenic dog food to determine which components must be evaded in the future.

Dog Food Allergies vs. Food Intolerance

It’s also essential to note the difference between an allergy and an intolerance. For example, suppose your dog cannot tolerate a specific type of food, such as lactose.
