SymptomsBy Mayo Clinic staff
Pet allergy signs and symptoms caused by inflammation of nasal passages include:
- Runny nose
- Itchy, red or watery eyes
- Nasal congestion
- Itchy nose, roof of mouth or throat
- Postnasal drip
- Facial pressure and pain
- Frequent awakening
- Swollen, blue-colored skin under your eyes
- In a child, frequent upward rubbing of the nose
If your pet allergy contributes to asthma, you may also experience:
- Difficulty breathing
- Chest tightness or pain
- Audible whistling or wheezing sound when exhaling
- Trouble sleeping caused by shortness of breath, coughing or wheezing
Some people with pet allergy may also experience skin symptoms. Allergic dermatitis is an immune system reaction that causes skin inflammation. Direct contact with an allergy-causing pet may trigger allergic dermatitis signs and symptoms, which may include:
- Raised, red patches of skin (hives)
- Itchy skin
When to see a doctor
Some signs and symptoms of pet allergy, such as a runny nose or sneezing, are similar to those of the common cold. Sometimes it's difficult to know whether you have a cold or an allergy. If symptoms persist for more than one week, you might have an allergy.
If your signs and symptoms are severe — such as severe nasal congestion, difficulty sleeping or wheezing — call your doctor. Seek emergency care if wheezing or shortness of breath rapidly worsens or if you are short of breath with minimal activity.
