Fighting the allergy. Is this all about the food?
"However, there are more serious cases where some dogs develop an allergy towards elements in their food or natural environment. Some dogs also have inhalant allergies. They can have skin problems such as itching and chewing on their skin because they have an allergic reaction to some kind of pollen or allergen that they inhale. These type of allergies are usually harder to combat as it will be difficult to determine the source of the allergen."
