Allergies in Dogs - Key Points and More





Allergies are the bane of modern life, a reality that's true for dogs and cats as well. Our understanding of allergies in dogs is continuously evolving, primarily thanks to pediatric literature. It's impossible to imagine what the future holds for the subject, with it so different now than it was 30 years ago.

The issue is vital from a broader perspective that doctors are now recommending exposure of traditional allergens like peanuts to children sooner than previously recommended. With that information going around, one can only imagine how we treat the issue with our dogs.

As a result, below will highlight common allergies in dogs, including the common signs and symptoms. We'll also discuss the specifics of how you can treat dog allergies and how we can potentially help you. Continue reading if your dog has allergies and wants to be prepared for the subject.

What are Common Signs and Symptoms of Allergies in Dogs?

Most dogs manifest allergies as skin issues, with areas commonly affected, including the paws, inner thighs, armpits and ears. Signs include redness, ear infections, hot spots, dermatitis, rash, foul odour, itchiness, and pustules ( bulging patch of skin that's full of a yellowish fluid). Most allergies will manifest in a dog 1 or 2 years old onward but can start sooner.

Global climate change and tree preference are making allergies worse in most cities around the globe. Canadian cities are no exception and are experiencing a higher pollen count, resulting in worsened allergies. In short, this is a rapidly evolving area of research, and yes, allergies may be getting slightly worse due to our modern lifestyle.

Common Signs and Symptoms

  • Redness

  • Ear Infections

  • Hot Spots

  • Dermatitis

  • Rash

  • Foul Odor

  • Itchiness

  • Pustules

What are the Most Common Allergies in Dogs?

The most common allergens are tree pollen, grass pollen, mildew, and dust mites. Look for seasonal patterns in your pet's allergies since the year significantly affects their overall allergies.

Food proteins or other components can also act as allergens nonseasonally. Some dogs can have both types of allergies, just as humans can to food and pollen. Lastly, insects like mosquitoes or fleas can also cause allergic reactions.

  • Pollen

  • Grass

  • Mildew

  • Dust Mites

  • Food Proteins

  • Insects

  • Parasites


Do All Dogs Have Allergies?

Though it may seem odd, unfortunately, most dogs experience allergies at some point. Like humans, the severity of the allergies varies depending on the dog. Thankfully, there are ways to treat the allergies, ranging from specific food trials to general antihistamines.

How Do You Treat Allergies in Dogs?



If you suspect your pet has food allergies, consider reaching out to a vet for proper guidance on how to do a food trial. In many cases, buying a specific protein food off the shelf is not good enough. Most manufacturers use the same lines to manufacture different pet food, resulting in contamination.

For other kinds of allergens, vets typically use a combination of omega oils, anti-inflammatory drugs, shampoos, and immunotherapy (sometimes called allergy shots). Like humans, individual dogs require different therapies to see what works best for them.

  • Food Trial

  • Omega Oils

  • Anti-Inflammatory Drugs

  • Shampoos

  • Immunotherapy
