It is possible to control allergies to the point that the animal does not present symptoms, i.e. it does not scratch. In cases of adverse reactions to food and allergies to flea bites, the treatment is to avoid the allergens (the ingredients involved in the clinical symptoms and the presence of fleas, both in animals and in the environment they live in).

In the case of canine atopic dermatitis (CAD), it is impossible to keep a written check of the presence of the environmental allergens involved, so we should make use of pharmacological therapies or immunotherapy. Immunotherapy should be considered the treatment of choice to control CAD.
