If you didn’t already know, pets can suffer from seasonal allergies too. As with many humans, the fall can trigger various allergic reactions as certain allergens are more prevalent during this time. We know you want to keep your pet safe and comfortable, so we’ll help you identify the most common autumn pet allergies, how to recognize allergy symptoms in pets, and what you can do for your furry friend if they struggle with seasonal allergies.

Most Common Autumn Pet Allergies 


Ragweed is a common weed that releases its pollen into the air during the fall months. It is a potent allergen for many pets, leading to symptoms such as sneezing, itching, watery eyes, and skin irritation.

Sagebrush, Lamb’s-Quarters & More

In addition to ragweed, sagebrush, lamb’s-quarters, and other weeds that pollinate in the fall can be problematic for dogs, as well. Allergic reactions to these plants can occur when dogs breathe in the pollen and when the pollen settles in their fur and on their skin.  


Fall is also a prime time for mould growth, especially in damp and decaying vegetation. When dogs inhale mould spores or they come into contact with their skin, it can cause allergic reactions, respiratory issues and skin problems.

Dust Mites

Dust mites can be present year-round, but they may become more of an issue during autumn when pets spend more time indoors. These microscopic pests can trigger allergic reactions in some animals, particularly affecting their respiratory system.

Pet Allergies: Signs & Symptoms

Signs and symptoms of pet allergies can vary from mild to severe and may affect different parts of the body. Here are some common signs to look out for:

  • Skin irritation or redness

  • Ear infections
  • Paw chewing and licking
  • Rubbing or scrubbing their face
  • Hives or rash

Treating Your Dog’s Autumn Allergies
