Diagnosis of food allergie and the victory over it

Food Allergy is the cause of every fifth case of itching and redness of the skin in dogs. It with the same frequency occurs in males and females, neutered and intact animals. The reaction may occur in Pets from five months to 12 years.

Animals often simultaneously suffer from airborne (particles in the air such as pollen or dust), and/or contact allergies. There is no connection between the breed of the dog and its reaction to certain foods.

A distinction should be made between a food Allergy and intolerance products. Food Allergy has typical symptoms in dogs are manifested in the form of scabies and other skin problems.

A food intolerance results in diarrhea or vomiting, but does not give the typical allergic reactions. It looks more like indigestion from eating spicy or fried food.

What to do?

Immediately start with the most interesting: to treat food Allergy is meaningless. Enough to achieve the exclusion from the diet of the allergen, and the symptoms will disappear. The immune response of the body to return to normal, and everything will disappear like a bad dream.

But first you will need to locate the source.

Suspicious products

Studies have shown that some ingredients more likely to cause food allergies than others.

The most rasprostranyaetsya in the diet for dogs:


Peshevi the symptoms of allergies like. The primary symptom is irritation on the skin of the muzzle, paws, ears, front legs, in the armpits and around the anus.

In addition, there may be chronic or recurrent ear infections, hair loss, constant scratching, red spots and skin infections. All these phenomena respond to antibiotics, but recurs after the termination of their employment.

It is proven that dogs with food allergies often have more frequent stools. One study showed that dogs do not suffer from allergies, defecate about 1.5 times a day, whereas animals exposed to food allergies – 3 times more often.

On the basis of physical symptoms difficult to distinguish food Allergy from other reactions.

A list of the most frequent symptoms:

Recurrent ear problems, particularly candidiasis;

The presence of a puppy and adolescence moderate or severe skin problems;

Third tip — if a dog suffers from allergies year-round or if symptoms begin to appear in winter (when the immune system is compromised);

And the last hint: the dog severely irritated skin, and treatment with drugs based on hormones doesn’t help.


Food Allergy is diagnosed very simply. However, many other health problems cause similar symptoms, and the animal often suffers from other illnesses.

So before you make the diagnosis and start any treatment, it is important to see to it that all other illnesses have been identified and eliminated. A simple Allergy, such as flea bites, hypersensitivity, caused by intestinal parasites, scabies and sudneva candidiasis, bacterial infection — all of which can give the same symptoms as food Allergy.

Elimination diet

Once possible causes are ruled out, it is necessary to perform testing unusual food.

It is to use a new kind of food for at least 12 weeks. This food must contain proteins and carbohydrates that the animal had not previously received.

For example, this could include rabbit and rice, venison and potatoes — such a diet of feed lot. In addition, there are special diets in which protein and carbohydrates have such a small molecular size that will not cause an allergic reaction. Vets call such experiments “limited antigen” and “diet based on hydrolyzed protein”.

You can also feed dogs home-cooked food, strictly limiting the number of ingredients.

Regardless of diet, are source of protein needs for 3 months become the sole food of the animal.

It is impossible to include in the diet:



pig ears;

a cow’s hoof;

flavored medications (including tablets from worms ) and the additive;

flavored toothpaste ;

plastic toys with the smell;

any food when giving medications.

In other words, the dog does not consume anything, except your chosen food and water with no exceptions.

If possible bring the rest of their animals on the same diet that the patient. If this is not possible, feed them in a different place and do not allow patient to touch their food.

When you go on your own, the dog must be in the other room. If she’ll eat a piece, dropped on the floor, or lick a plate, you have to start the test again. After small children (if they are in the family) meal, wash their hands and face.

Do not allow pet to wander on the street, always keep him on a leash during walks .

Keep a journal and record in it the date and the food that your pet could accidentally eat it.

The timing of the test

Previously, the vets recommended to put your pet on a special diet for three weeks, but new research showed that only 26% of dogs with food Allergy reaction occurs on day 21 or earlier.

However, the vast majority of animals showed an allergic reaction after 12 weeks. It is therefore very important to keep your pet on a diet throughout this time.

If the dog demonstrates a reduction or complete disappearance of symptoms, return to her ordinary diet. This process, called “provocative testing” is very important to confirm the diagnosis.

If after returning to the stern old symptoms appear again, food Allergy is definitely confirmed. If changes in symptoms is not observed, but still have a strong suspicion, you can try another test using a different unfamiliar food.

Laboratory studies

Keep in mind that at the moment there is no evidence that the blood test accurately detects allergies to food.

Intradermal Allergy tests are coping with the diagnosis of a simple (airborne) allergies, but ineffective when it comes to food.

The only way to make an accurate diagnosis is to resort to the help described above the elimination diet.
