Protecting pets from wildfire smoke: What you need to know
by Ontario SPCA and Humane Society | General Pet Care | June 19, 2025

With many parts of Canada affected by wildfires, it’s important to take extra precautions to protect your pets from the harmful effects of smoke. Just like people, animals are at risk of respiratory issues and other health concerns when air quality is poor.
Safety considerations
Limit outdoor time as much as possible. While bathroom breaks are necessary, avoid long walks or extended playtime outside. Check your local air quality advisories and keep pets indoors as much as possible whenever conditions are poor.
Protect your home environment by closing windows and doors to keep smoke out. Use air purifiers with HEPA filters if available and run your air conditioner in recirculation mode to prevent bringing in outdoor air. If you notice signs of smoke irritation in your pet—such as coughing, red or watery eyes, sneezing, lethargy, or trouble breathing, contact your veterinarian right away.
Certain animals are more vulnerable to smoke, including flat-faced breeds like pugs, bulldogs, and Persian cats. Puppies, kittens, senior animals, and pets with pre-existing medical conditions are also at increased risk. Be especially cautious and consult your vet if you’re unsure how to best protect them.

Be prepared
If you must evacuate, take your animals with you. Have a plan in place to evacuate your family, including your animals, as early as possible. Evacuating before conditions become severe helps keep everyone safer and reduces stress levels. Learn how to include your pet in your emergency plan.
Smoke from wildfires can be dangerous—but with the right steps, you can help keep your animals safe and healthy. Stay informed, be prepared, and don’t forget to check in on your furry friends.
