The 8 most common allergenic foods for dogs

See Dogs files

Our dog's diet is very important for his health and we must pay enough attention to it. Some dogs do not present food allergies and they can ingest feed formulated with different ingredients, while other dogs suffer from food hypersensitivity and are affected by different types of food.

Before the presentation of dermatological signs in our dog, this type of allergy must be ruled out. Next, we will know in this AnimalWised article the 4 most common allergenic dog foods.

Food allergy in dogs and other concepts:

There are many foods that can cause an allergy to our best friend, but below we are going to show you the 4 most common allergenic foods for dogs:

  1. Veal
  2. Chicken
  3. Dairy products
  4. Fish
  5. Pork
  6. Wheat
  7. Corn
  8. Soy

Since the clinical symptoms are similar to those caused by other diseases, a correct differential diagnosis with:

  • Endocrine diseases such as hypothyroidism
  • Parasitic diseases such as sarcoptic mange or demodectic mange
  • Other allergic diseases such as reaction to environmental allergens (atopic dermatitis) or flea bite
  • Fungal infections (dermatophytes)

Contributing factors

Some of the factors that contribute to food allergy are bad digestions, that is, the longer the food spends in the intestine, the more exposed it is to immunoglobulins E and the probability of triggering the anaphylactic response increases. However, the increased permeability of the intestine it can also contribute: if the dog is parasitized, the permeability of the wall is increased, thus increasing the absorption of allergenic proteins.

Food allergy symptoms and diagnosis:

The main sign of a food allergy is dermatological in nature: non-seasonal itching, that is, the dog is itchy regardless of the time of year. Secondary to that itchiness, pyodermas (skin infections) form. There are also other signs, although less frequent, such as diarrhea, vomiting, etc..

Food allergy can be accompanied by other allergies such as those discussed in differential diagnoses.

Diagnosis

There are several allergy tests for dogs, including the elimination diet. For a minimum period of two months, the dog should be fed a diet of this nature.

These diets are made with exotic proteins to which the dog has not been exposed (deer, horse, rabbit, etc.) and carbohydrates such as potatoes or rice, or highly hydrolyzed proteins (due to its small size the immune system does not detects them and does not trigger the immune response). You can make a homemade diet, but always under the supervision of our veterinarian so that there is no lack of nutrients.

After this period, a provocation test. In other words, the dog is fed the diet that we believe caused the symptoms and the evolution is observed. If after this provocation, the dog begins to pruritus, we will perform the elimination diet again and then confirm the diagnosis.

Treatment

The treatment to follow is to feed the dog with protein and / or carbohydrates that do not cause allergies. For this, our veterinarian can indicate a homemade food for allergic dogs specifically formulated, but we can also choose to hypoallergenic feed for dogs, also supervised by the specialist.
