For this, the dogs rub more in the eyes and nose, which are also perceived as itchy.
As an additional symptom Interdigitated toe granulomas. These are nodules that arise from inflammatory cells and form in the spaces between toes. Often the granulomas are found when the immune system against something worth. Infection, foreign body or even allergen can be the trigger. Just as often appear the Hot spots. They are round, oozing and moist spots. They appear suddenly at the back of the back or in the area of the neck and cheeks.
Make the diagnosis: Food allergy in dogs
But whether it is really a food allergy requires an intensive conversation with the veterinarian. If possible all circumstances are questioned. Because the symptoms can also be signs of parasites and other diseases. Can be Body examination If parasites and other skin diseases such as yeast fungi are excluded from the dog, it is checked whether it is an allergen. If the veterinarian has diagnosed the food allergy in the Suspicion, he will confirm it with the help of an exclusion diet. Blood tests are not done at this point, because the results are not clear enough.
The confirmation of the diagnosis
In order to confirm the food allergy, under the supervision of the veterinarian, a Exclusion diet carried out. As a rule, the diet takes place over a period of 6 to 10 weeks. The longer, the better. The right food should be chosen for the test period. Ideally, only ingredients that do not cause an allergic reaction should be used. This can be confirmed by three different methods. In one variant, one uses exclusively food that has never been used before. However, since most dog owners choose menus with many different ingredients, this option is much more difficult to. The other method is a hydrolyzed diet. This means foods whose molecules are too small for the immune system's recognition system. Alternatively, the dog owner can cook for the dog themselves.
Important is the Test period to be carried out consistently. This is the only way to determine whether it is really an allergy to a food. Immediately after completion, the veterinarian can see whether the symptoms have improved or not. If the result is not completely clear and no other Disease pattern suitable, one tests after certain time again after the exclusion procedure.
If the symptoms improve noticeably during the exclusion diet, then the suspicion of a food allergy is confirmed. Finally, the diagnosis is certain by testing the dog again with the Feeding habits confronted by before the process of exclusion. If the symptoms worsen again, the allergy is considered to be confirms.
The dog life with food allergy
Which allergen is responsible for the food allergy is still unclear. To be able to narrow down the trigger, one tests step by step feed used so far. If possible, always feed only one allergen to the dog. So the dog owner gets a view of what the dog actually tolerates. one starts in most cases with a grain-free dog food.
Causes of feed allergy
To date exact allergen, that is responsible for feed allergies, unknown. It is certain that several factors were responsible. Influences from the environment. Environment is such a factor. Gladly referred to as an environmental allergy. In the process, the immune-. weakened digestive system of the dog. A free pass to make the dog allergic to different food sources. Therefore, food allergy is often seen as a side effect of other allergies.
Difference between allergy and intolerance
In the Symptoms, the diagnostic test and in lifestyle, there is no difference between a food allergy and an intolerance. From a purely technical point of view, however, there is a difference between the two Differences. With good reason – but why?
If an intolerance is meant, the dog reacts immediately to the triggering substance. Without any involvement of the immune system. Often an intolerance is reflected in the stomach – intestine – tract. Flatulence and diarrhea are characteristic. Triggered by a missing enzyme that prevents the food from being processed. The best known example is the intolerance of milk (lactose intolerance). This is why food intolerance is often referred to as food intolerance. Mostly a food intolerance is inherited. Is present with it in the hereditary information.
Triggering substances in the feed for dogs
With an allergy it looks different. Before an allergic reaction occurs for the first time, the dog has already had contact had with the triggering substance. The immune system forms antibodies against the trigger, which can be detected. An overreaction caused by the newly formed body's own defenses is the consequence. Possible causes are many. A conspicuous accumulation to suffer even from a food allergy there is with the dogs whose parents suffered even from a food allergy. Viral diseases, parasites and feeding errors also contribute to allergy-related intolerance. Again and again a primary. Secondary allergy spoken. The detail is in the time. In the case of a primary food allergy, the dog reacts immediately or. very promptly. If one speaks of the secondary allergy, the dog had already eaten over a longer period from the food. If such a case occurs for the first time, one does not always think of the food immediately. An indication that dogs also suffer from food allergy in old age for a long time Suffer unnoticed from a feed allergy can.
