If you love dogs but suffer from allergies, you’re not alone. Millions of people experience sneezing, itchy eyes, and congestion when around dogs. The good news is that there are many effective treatments available.
What Causes Dog Allergies?
Dog allergies happen when your immune system reacts to proteins found in:
- Dander(dead skin flakes)
- Saliva(from licking or drooling)
Urine
The main allergens are proteins called Can f 1 and Can f 2, which stick to fur, clothes, and furniture. When you breathe in or touch these allergens, your body releases histamines, causing symptoms like:
- Sneezing
- Runny or stuffy nose
- Itchy, red eyes
- Skin rashes or hives
- Coughing or wheezing (in severe cases)
Some people have mild reactions, while others experience severe symptoms. The right allergy medicine can make a big difference.
5 Types of Dog Allergy Medicines
There are several types of medications to treat dog allergies:
Antihistamines
Block histamine, reducing sneezing, itching, and runny nose
Available as pills, liquids, nasal sprays, and eye drops.
Decongestants
Shrink swollen nasal passages for easier breathing.
Often combined with antihistamines.
Corticosteroids (Steroids)
Reduce inflammation in the nose, lungs, or skin.
Available as nasal sprays, inhalers, creams, or pills.
Leukotriene Inhibitors
Block chemicals that cause swelling and mucus production.
Often used for asthma-related allergies.
Allergy Shots (Immunotherapy)
Long-term treatment that helps your body get used to allergens.
Requires regular visits to an allergist.

- Severity(mild, moderate, or severe).
- Side effects(drowsiness, dry mouth, etc.).
