Dogs and cats can be allergic to everything that irritates us and more. Though the skin is the largest organ of the body, it is very limited in the manner in which it can respond to allergens. Itching is the most common reaction.
You might also see dandruff, incessant licking or biting of the paws, hair loss in only one spot or a generalized thinning of the coat. Additionally, allergies can also lead to chronic ear infections, occasionally in only one ear.
