Dog dermatitis | My dog ​​scratches a lot, what's wrong?

It is very common in the fall for pet owners to notice that their dogs begin to scratch excessively or compulsively to the point of injury. And it is that the change of season can increase the appearance of allergies in dogs and cats, especially in the skin. The itching and irritation of our pet's skin are the most obvious symptoms of dermatitis in dogs.

This occurs because the increase in airborne dust caused by falling leaves can trigger your dog's allergies. So many owners go to the vets with the following statement: my dog ​​scratches a lot.
