What Causes Dog Allergies?

Dog allergies are caused by an immune system response to something that’s inhaled, ingested, or touched. Common allergens include dust mites, pollen, mold, and certain foods. Dogs can also be allergic to flea bites, certain fabrics, and even their own saliva.

The signs and symptoms of dog allergies vary depending on the type of allergen and the severity of the reaction. Common signs and symptoms of dog allergies include:

• Itching and scratching

• Red, inflamed skin

• Hair loss
• Hot spots
• Excessive licking or chewing
• Sneezing and coughing
• Watery eyes
• Vomiting and/or diarrhea

How to Prevent Dog Allergies

The best way to prevent dog allergies is to reduce your dog’s exposure to allergens. Here are some tips for reducing your dog’s exposure to allergens:

• Keep your home clean and free of dust, pollen, and mold.
• Vacuum regularly and use a HEPA filter to reduce airborne allergens.
• Wash your dog’s bedding regularly.
• Avoid using fabric softeners or scented laundry detergents.
• Use flea preventatives to reduce the risk of flea allergies.
• Feed your dog a hypoallergenic diet.
• Avoid giving your dog treats or snacks that contain common allergens.

How to Treat Dog Allergies

If your dog has allergies, there are a number of treatments available to help relieve the symptoms. Here are some of the most common treatments for dog allergies:


Antihistamines are often the first line of treatment for dog allergies. Antihistamines can help reduce itching, sneezing, and other allergy symptoms.


Corticosteroids are powerful anti-inflammatory medications that can help reduce itching and swelling associated with allergies.


Immunotherapy, also known as allergy shots, can help reduce a dog’s sensitivity to allergens. This treatment involves administering small doses of the allergen over time, gradually increasing the dose until the dog is no longer sensitive to the allergen.

Allergen-Specific Immunotherapy

Allergen-specific immunotherapy (ASIT) is a form of immunotherapy that is tailored to a dog’s specific allergies. This treatment involves administering small doses of the specific allergen that is causing the allergic reaction.


Dog allergies can be a nuisance, but they don’t have to be. By reducing your dog’s exposure to allergens and using appropriate treatments, you can help prevent and treat dog allergies. If your dog has allergies, it’s important to consult with your veterinarian to determine the best course of action. With the right treatment plan, you can help keep your dog comfortable and symptom-free.
