Atopic Dermatitis (Environmental Allergies)

What is it?

Atopic dermatitis is an inherited tendency to overreact to things in the environment, such as pollens, molds, and dust mites. The skin barrier is weaker than normal, so allergens get in and trigger itching. Signs often begin between one and three years of age.

What signs should I watch for?

Signs to watch for include licking or chewing the paws; scratching the face, ears, belly, or armpits; red skin, hair loss, or darkened skin; and recurrent ear or skin infections.

How is it diagnosed and treated?

Diagnosis is made by ruling out look-alikes such as fleas, mites, and food allergy. Allergy testing helps select allergen-specific immunotherapy. Management combines itch-control medications, medicated bathing, skin-barrier support, and treatment of secondary infections.

Can it be prevented, and what's the outlook?

• Allergies are managed rather than cured, but most dogs can be kept comfortable.
• Florida's long pollen and mold seasons, plus year-round fleas, make consistent flea control and follow-up especially important.
