What are common dog allergies?

Symptoms may include sneezing, an itchy or blocked nose, watery or itchy eyes, coughing, wheezing or an itchy rash after contact with a dog or a dog’s environment. Hair can carry allergens, but the trigger is usually a protein rather than the hair itself. Symptoms may be stronger indoors, where allergens can remain on clothing, furniture and other surfaces.

A reaction after meeting a dog does not prove that the dog is the cause. Dust, pollen, cleaning products or another animal can produce similar symptoms. A clinician can take a detailed exposure history and decide whether allergy testing is useful.

Keep the dog out of sleeping areas, wash hands after contact and avoid touching your eyes or face. Clean surfaces and fabrics regularly, and ask another person to groom or clean areas where possible. A GP or pharmacist can discuss suitable treatment for nasal, eye or skin symptoms. Do not start or stop prescription treatment without advice.

Call emergency services for sudden breathing difficulty, throat or tongue swelling, trouble swallowing, faintness, confusion or widespread hives with other symptoms. These can be signs of anaphylaxis. For recurring wheeze, persistent cough, skin reactions or symptoms affecting sleep, arrange a GP consultation for assessment.

Could my symptoms be caused by a dog or another allergen? Would allergy testing help? What should I do if breathing symptoms occur, and which treatment is suitable for regular exposure?
