What You Need to Know About Allergies in Dogs

Theoretically, your dog could develop an allergy to just about anything he ingests, comes into physical contact with, or breathes in. Dogs can also develop allergies to flea bites.

Here are the four different types of dog allergies:

  • Environmental – Also known as atopy, environmental allergies come from the world around your dog. These can include everything from mold, dust, and pollen to cigarette smoke, perfume, cleaning products, and certain fabrics.
  • Food – The most common food allergens for dogs are grains, dairy, legumes, and common proteins like beef, chicken, eggs, pork, and fish. Food allergies can sometimes affect the digestive system, causing vomiting or diarrhea, but they can also lead to skin-related symptoms such as dry, itchy skin and irritation or inflammation.
  • Flea – Flea allergies are not caused by the flea itself but by the flea bite. Even a few flea bites can cause serious irritation and itching for your dog, so it is important to use flea prevention.
  • Contact – The most common contact allergies for dogs is to certain types of fabrics, though they can also be caused by dander produced by humans and other animals.
Environmental allergies are often seasonal, getting worse during the times of year where common allergens like pollen are more pervasive. Symptoms of seasonal allergies may include red, itchy, or moist skin as well as irritation, scratching, and itchy eyes. Flea allergies may not be seasonal, but they are more likely to be a problem during the warmer months when fleas are more common. Food allergies and contact allergies, on the other hand, can happen any time of year.

The first step in diagnosing your dog’s allergies is to talk to your veterinarian. Your vet will likely perform a combination of blood tests, skin tests, and saliva tests to determine the cause of your dog’s allergies. From there, you’ll be able to determine the best course of treatment. For food allergies, it is generally a matter of identifying and then eliminating the offending ingredient. For other allergies, you may simply need to take steps to avoid them. In severe cases, your dog may need to take some kind of allergy medication or receive an allergy shot.

Another element of treating allergies in dogs is dealing with the skin-related symptoms. Dietary changes to eliminate the offending allergen from your dog’s diet can take weeks to take full effect and even if you take steps to avoid contact and environmental allergens, you may not be able to avoid them entirely. To relieve your dog’s itching and irritation, an allergy dog shampoo might help.

FAQ Regarding Allergy Shampoos

To bathe him, start by brushing his coat gently to remove any dead or loose hair as well as allergens that may be settling into his coat. Use a hypoallergenic dog shampoo and cool water, making sure to work the shampoo into his coat – you may even need to let it sit for a few minutes if it’s medicated, so your dog gains the maximum benefit. When you’re done, rinse thoroughly and let your dog’s fur air dry to avoid over-drying it with the blow dryer.
