Atopic dermatitis (AD) is a chronic, relapsing inflammatory and pruritic skin disease that affects approximately 10–15% of the dog population. It is associated with abnormalities in skin barrier function and an underlying genetic predisposition to develop IgE antibodies against environmental allergens such as house dust mites, mold spores, and grass pollens. Unlike food allergies, atopic dermatitis tends to follow a seasonal pattern early in the disease course before often becoming year-round as sensitization to additional allergens occurs.
Clinical signs typically include itching, redness, and recurrent skin and ear infections. Commonly affected sites include the face, paws, ears, groin, and armpits. The hallmark symptom is pruritus — intense itching that can severely impact a dog's quality of life and lead to secondary bacterial or yeast infections if left untreated. Owners often describe their dogs as constantly licking paws, rubbing faces on furniture, or scratching at ears.
Management of canine atopic dermatitis requires a multimodal approach. First-line interventions typically include anti-pruritic therapies such as Apoquel (oclacitinib) or Cytopoint (lokivetmab), combined with targeted topical care to support skin barrier recovery. Products like AtopiCream HC provide leave-on hydrocortisone combined with ceramides and essential fatty acids to calm inflammation and help rebuild the lipid barrier. Regular bathing with a therapeutic shampoo such as Command Deep Cleansing Shampoo can also reduce microbial burden and provide itch relief between flareups. Working closely with a veterinary dermatologist is recommended for moderate to severe cases.
