How is the allergy diagnosed in dogs?
Modern veterinary science is equipped with sufficiently informative laboratory methods, equipment and reagents. However, it is difficult to diagnose allergy in animals with the biochemical method due to the peculiarities of the immune system. The basic method of identifying allergies as the cause of the symptomatology of unclear etiology is the food test. From the nutrition of the dog, whenever possible, all possible types of supplements are excluded, there are only two - the source of protein and the source of carbohydrates. If the symptoms disappear with this diet, the test results are considered positive. As a rule, testing lasts no less than 4 weeks and can last two months. If the test is positive, the dog again receives a normal set of products, which she was fed before the test. In the case of the resumption of allergic symptoms, the diagnosis of allergy is beyond doubt. It is also necessary to carefully inspect the animal before testing to exclude the presence of external parasites (fleas), and anthelminthic prophylaxis is also performed. All these measures are designed to ensure that testing is most accurate, informative and not distorted by false results not associated with allergies directly. In addition to the dietary test, provocation is practiced. The process looks like this: for 7-10 days in the dog food gradually add up the possible provocative products and track the symptoms. As a rule, the reaction occurs quickly enough, not later than the second day of the test. If there are no symptoms, you should look for the cause of the disease in another way and eliminate allergies. Basically, the provocation is carried out using protein products - eggs, meat, fish, whole milk products, then raw vegetables are added. This is how the individual diet and diet is made, which excludes the presence of provocative components in the dog's diet.
