Symptoms that the dog is allergic to the feed

The food allergy in dogs appears suddenly, appearing normally between the year and three years, however the animal can begin to manifest the symptoms of allergy to the feed later, at an advanced age. This happens basically because the body of the animal can be sensitive to a specific food or compound, but it is as it is exposed very often to that particular detonator that develops a hypersensitivity to it, finally the animal's immune system will eventually identify that substance as a foreign agent, giving rise to all the symptoms of an allergy.

Although you do not believe it, your dog can become allergic to a feed that has been eating for years just because it contains one or several ingredients that produce the symptoms. This situation can be quite sudden, in the same way that happens in humans, who can become allergic to a food that they have always eaten without problems.

The first step to know if your dog is allergic to the feed is to determine the symptoms that the animal presents. Some of the common signs that denote a food allergy are:

  • Itching prolonged and without any relation to the station. In spring or autumn many dogs can suffer discomfort in their skin due to allergens such as pollen or dust, which also affect them. But in the case of food allergies the pruritus occurs at any time of the year and without apparent cause, there are no fleas, or any other parasite or condition that may explain why the animal scratches so much. Itching can occur in localized areas or throughout the body.
  • Frequent or continuous diarrhea.
  • Vomiting, may be occasional or frequent.
  • Difficulty breathing.
  • Bloating or tearing more abundant than usual.
  • Coughing and sneezing may occur.
  • In some cases the animal also manifests infections such as ear infections, due to the weakening of the immune system.

Food compounds that can cause allergies in the dog

  • The wheat

  • The pulp of the beet
  • Meats like veal, chicken or horse meat
  • Milk or dairy products

Identifying which ingredients the dog is allergic to is basic, because even the hypoallergenic feed may contain traces of a product that causes allergy in the animal, and therefore the change will not produce the expected effect or improvement.

Diagnosis and treatment of food allergies in dogs

Once we suspect that the dog has an allergy, the next step is to go to the vet . Vomiting and diarrhea, along with constant itching, can show that it is a food allergen, however it is the veterinarian who must diagnose the problem.

What is the elimination diet?

The veterinarian chooses a specific diet that the dog must follow for at least 8 to 12 weeks. The diet must be followed to the letter and never be broken, therefore the animal should not receive a single croquette, prize, commercial food or anything that is not included in the diet that has been prepared for it. otherwise the results could be altered. If indeed the problem is the feed, with the elimination diet the symptoms should disappear and, when the animal returns to the feed that was consumed before, they will appear again after a few days and even hours, a sign that the problem is in the food.

From there the veterinarian will provide the indicated feed for the dog and will inform which products should disappear from the animal's diet.
