What are the age of onset and breed predilections for atopic dermatitis in dogs?
Age of onset is 6 months to 3 years. Breed predilections include WHW terrier, Labradors, French/English bulldogs.
What are the clinical features of atopic dermatitis in dogs?
Classically, atopic dermatitis presents as chronic relapsing pruritic dermatitis, usually responsive to glucocorticoids. Initially, there may be erythema and papules, which can progress to self-induced alopecia and excoriations. The affected areas are usually the ears/face, feet, carpi/tarsi, axillae/inguinum, ventrum, and perineum. It is often associated with recurrent secondary pyoderma/Malassezia infections.
What is food-induced atopic dermatitis in dogs?
Food-induced atopic dermatitis, also known as 'food-responsive dermatosis', refers to an immunological reaction to dietary allergens or non-immunological reactions to diet, which can cause dermatological clinical signs identical to environmental atopy.
How does food-induced atopic dermatitis differ from environmental atopy in dogs?
Food-induced atopic dermatitis has less known about its pathogenesis compared to environmental atopy, and it is less common.
What is the term used to describe atopic dermatitis triggered by dietary allergens in dogs?
The term used to describe atopic dermatitis triggered by dietary allergens in dogs is food-induced atopic dermatitis.
What are the clinical manifestations of atopic dermatitis in dogs?
The clinical manifestations of atopic dermatitis in dogs include chronic relapsing pruritic dermatitis, erythema, papules, self-induced alopecia, excoriations, and recurrent secondary pyoderma/Malassezia infections.
What is the typical response to glucocorticoids in dogs with atopic dermatitis?
Dogs with atopic dermatitis usually show a positive response to treatment with glucocorticoids.
