Cause: Inhaled substances such as dust mites and pollens (atopy or allergic inhalant dermatitis, an inherited condition); flea saliva (flea allergy dermatitis); contact with or ingestion of a triggering substance, including food ingredients.
Symptoms: Itching (often severe); skin rashes ranging from slight reddening to generalized inflammation with assorted bumps, pimples, and welt-like lesions; persistent ear infections. Secondary infections by bacteria and yeasts are common.
Treatment: Allergen avoidance, flea control, antihistamines, corticosteroids (“cortisone”), cyclosporine, and hyposensitization (“allergy shots”). Antibiotics and anti-yeast medications are used to treat secondary infections. Often a combination of therapies produces the best results.
