Did you know? Allergies don’t only affect humans; dogs can suffer from them too! Understanding dog allergies will help keep your furry friend healthy and happy. Let's dig in!

Dogs Can Be Allergic, Too

Many pet owners are surprised to learn that dogs can develop environmental allergies, including sensitivities to pollen, mold, dust mites, and even human dander. When it comes to allergies, pollen can be a big challenge for dogs. Dogs with allergies to pollen often exhibit symptoms like incessant scratching, ear infections, paw licking, or skin inflammation, especially in the spring and fall.

These reactions are similar to human seasonal allergies, but sometimes dogs may require medical treatment from a vet. Treating dog allergies often involves antihistamines, medicated shampoos, dietary changes, or immunotherapy—also known as allergy shots (Yes! Dogs can get them too!). Some dogs may benefit from cytopoint injections or oral medications that block itch signals at the neural level.

When Humans React to Dogs

For humans, allergic reactions to dogs are commonly triggered by proteins found in a dog's dander (dead skin flakes), saliva, and urine—not the fur itself, as many believe. A dog saliva allergy, for example, can cause hives, eczema flare-ups, or itchy skin where the dog licked. In more severe cases, exposure might lead to wheezing or even asthma attacks.

Those allergic to dog saliva symptoms often feel worse when playing with puppies, whose playful behavior often involves a lot of licking! Allergy to puppy saliva may feel stronger due to relatively more frequent contact.

Choosing the Right Dog for Sensitive Households

Many people assume some dogs are hypoallergenic, but no breed is 100% allergy-free. However, some breeds are considered better for allergy sufferers due to lower production of allergenic proteins or because they shed less dander. These breeds include Poodles, Bichon Frise, Portuguese Water Dogs, and certain terriers.

For individuals with allergies looking for dogs, it’s even more important to spend time with the breed before adopting. Reactions vary from person to person, even within the same household. 

To help manage pet allergies, experts recommend keeping dogs off furniture, using HEPA air purifiers, and bathing pets regularly to reduce dander.

Dust Mites and Dual Sensitivities

Another well-known allergen that poses challenges for people sensitive to dogs is the humble dust mite. Found in carpets, bedding, and upholstery, dust mites thrive in warm, humid environments and feed on skin flakes—both human and pet.

For humans and their dogs who share allergic sensitivities, dust mite allergy treatment is essential. While medical treatment is one option, environmental mitigation is the first line of defense. This includes:

  • Using allergen-proof bedding and mattress covers
  • Washing bedding weekly in hot water
  • Removing wall-to-wall carpeting when possible
  • Regular vacuuming with HEPA-filter vacuums
  • Dehumidifying the home
  • Using Pacagen's Dust Mite Allergen Neutralizing Spray

Using a HEPA air purifier for allergies can dramatically reduce the presence of airborne allergens, especially pet dander and dust mite debris. While dogs can also be allergic to dust mites, it's important to note that they are allergic to different allergens than us humans.

Final Thoughts: Shared Air, Shared Care

Dogs are more than pets—they’re companions, family members, and even emotional anchors. For households navigating the complexities of allergies—whether in pets or people—it’s reassuring to know that symptom control is achievable. Collaboration with a veterinarian and an allergist ensures both you and your dog can breathe easier.
