Understanding Dog Allergies and How to Treat Them

Posted by Oreo the Labrador on Sun, Sep 11, 2022

Dog allergies are a common issue for pet owners. While many people assume that all pet allergies stem from the fur or dander of the animal, this isn’t always the case.

In fact, a number of other substances can be the source of a pet allergy.

What Causes Dog Allergies?

The most common cause of dog allergies is dander, which is the dead skin cells that are shed by dogs. These cells contain proteins that can cause an allergic reaction in people who are sensitive to them. In addition to dander, other proteins in a dog’s saliva, urine, and even their fur can cause an allergic reaction.

The severity of the reaction can vary depending on the person’s individual sensitivity. In some cases, the reaction is mild and can be treated with over-the-counter antihistamines or other medications. In other cases, the reaction may be severe and require medical attention.

Symptoms of Dog Allergies

The most common symptom of a dog allergy are:

Itchy eyes: This is the most common symptom of a dog allergy, and it can range from mild to severe. Itchy eyes may be accompanied by redness, swelling, and watery discharge.

Runny nose: A runny nose may occur alongside itchy eyes, and can be accompanied by sneezing, coughing, and a feeling of congestion in the sinuses.

Wheezing: This is a more serious symptom of a dog allergy, and is caused by the lungs reacting to the allergens. It can cause a person to struggle to breathe.

Hives: Hives are raised, itchy, red welts on the skin that can be caused by an allergic reaction.

Difficulty breathing: In more severe cases, a person may experience difficulty breathing due to the lungs reacting to the allergens.

Swelling of the face, lips, or tongue: Swelling of the face, lips, or tongue can also be a sign of a serious allergic reaction.

Diagnosing Dog Allergies

If you think you may have a dog allergy, it’s important to consult your doctor for a proper diagnosis. Your doctor may do a skin prick test or a blood test to determine if you have an allergy. Once the allergy has been confirmed, your doctor can discuss treatment options with you.

Treating Dog Allergies

The most common treatment for dog allergies is avoidance. This means avoiding contact with the dog, as well as its dander, saliva, and urine. This may be difficult, especially if you own the dog or if you have a family member or friend who owns one.

If avoidance is not an option, then there are several other treatments that can help reduce your symptoms. These include antihistamines, decongestants, and steroids. In more severe cases, your doctor may prescribe an allergen immunotherapy, which is a series of injections that can help desensitize your body to the dog’s allergens.

Other Ways to Reduce Allergic Symptoms

In addition to avoiding contact with the dog and taking medications, there are a few other steps you can take to reduce your allergic symptoms. These include:

  • Vacuuming frequently and using a HEPA air filter to reduce the amount of dander in the air.

  • Washing your hands and face after contact with the dog.

  • Washing your pet’s bedding and toys regularly.

  • Keeping the pet out of the bedroom, if possible.

  • Not letting the pet lick you or sit on furniture.


Dog allergies can be a serious issue, but with the right treatment and management, you can reduce the severity of your symptoms and enjoy a better quality of life. If you think you may have an allergy to a dog, it’s important to consult your doctor for a proper diagnosis and treatment plan.
