Human allergy to dogs: symptoms, testing and practical steps

Allergens can cling to fur, clothing, furniture and household dust, so symptoms may continue after a dog has left a room. Common reactions include sneezing, a blocked or runny nose, itchy or watery eyes, coughing, wheezing, or itchy skin after contact. A dog allergy is different from irritation caused by dust or perfume, and allergy testing can help identify the trigger. Nasal symptoms may resemble Allergic Rhinitis, while eye symptoms may fit Allergic Conjunctivitis. The presence of symptoms after contact does not prove that a dog is the cause.

Keep the dog out of the bedroom, wash hands after touching it, and change clothes if exposure has been prolonged. Clean surfaces and fabrics regularly, improve ventilation, and avoid allowing the dog onto beds or upholstered furniture. A clinician may suggest a non-drowsy antihistamine, a nasal spray, or an inhaler when appropriate; use these according to their directions. If symptoms are frequent, ask about allergy testing and an individual plan. People with asthma should discuss wheeze or chest tightness because pet exposure can aggravate Asthma.

Arrange medical advice for persistent congestion, repeated wheezing, disturbed sleep, or symptoms that interfere with work or exercise. Seek emergency help for severe difficulty breathing, swelling of the lips or tongue, faintness, confusion, or rapidly worsening symptoms. These can signal a serious allergic reaction, including Anaphylaxis, and should not be managed by waiting at home.

Ask whether your pattern suggests dog allergy, which test is suitable, whether medicines are safe with your other conditions, and how to protect your eyes and lungs during unavoidable exposure.
