Lesson 2: Understanding Atopic Dermatitis

Put simply, atopic dermatitis (AD) is an allergic response that causes a dog’s skin to become inflamed, itchy, sore, and prone to infection. It’s also known as atopy and allergic skin disease.

Atopic dermatitis is very common in dogs, affecting about 1 in 10 dogs. It’s usually diagnosed in dogs between 6 months and 3 years old. It’s what’s known as a ‘progressive’ disease, meaning it often gets worse over time, usually as animals become allergic to more things.
