Wildfire Smoke Season: Protecting Your Pet’s Respiratory Health in Central Oregon

Medically Reviewed by Dr. Lauren Stayer, DVM on August 17, 2026

When the skies over Bend turn gray, and the smell of smoke settles into the Cascade foothills, humans aren’t the only ones who feel the effects. Dogs and cats breathe in the same fine particles that fill the air during wildfire season, and for many pets, that exposure can lead to real respiratory distress. Central Oregon’s dry summers and surrounding forests make wildfire smoke a recurring seasonal reality, and knowing how to protect your pet during these conditions can make a big difference in their health and comfort.

Pawtown Veterinary Care serves pet owners across Bend and the rest of Central Oregon, where an active outdoor lifestyle is part of daily life for most families and their animals. Dr. Erin Miller and Dr. Lauren Stayer, the owners and veterinarians at Pawtown, are part of this community and know how disruptive wildfire season can be for local pet owners. Whether you have an active hiking dog or a house cat who loves to lounge near an open window, our veterinary team is here to help you keep your pets safe and healthy all summer long.

How Wildfire Smoke Affects Dogs and Cats

Wildfire smoke contains a complex mix of gases and fine particulate matter, most of it small enough to penetrate deep into the lungs. Dogs and cats have a more acute sense of smell than humans, which means they may draw in more airborne particles with each breath. According to the Cornell University College of Veterinary Medicine, common signs of smoke exposure in pets include coughing, gagging, a fast respiratory rate even while at rest, and difficulty breathing. Like people, their eyes may also become red, watery, or irritated, and some pets develop a reduced appetite or noticeable fatigue during heavy smoke days.

Which Pets Are at Greater Risk

Some pets are at greater risk than others. Flat-faced breeds, including Bulldogs, Pugs, and Persian cats, already deal with compromised airways, which makes smoke exposure more dangerous for them. Senior pets, very young animals, and those with underlying heart or lung conditions should also be monitored closely during any period of poor air quality, and a senior pet wellness visit before smoke season is a good way to catch any existing respiratory or cardiac concerns early. If you notice signs of respiratory distress in your dog or cat, do not wait to see if it resolves on its own.

Practical Steps to Protect Your Pet During Smoke Events

When air quality alerts are issued in Central Oregon, the most effective thing you can do is limit your pet’s time outdoors. Here are several steps that can help reduce your pet’s exposure to smoke and keep them more comfortable indoors:

• Limit outdoor time: Restrict walks and other outdoor activities to brief bathroom breaks only. Skip trail runs, fetch sessions, or off-leash playtime until conditions improve.
• Keep windows and doors closed: Prevent smoky outdoor air from drifting indoors, especially during peak afternoon hours when air quality tends to be worse.
• Use air purifiers: Running a HEPA air purifier indoors can help reduce the concentration of fine particles your pet breathes throughout the day.
• Watch for coughing or labored breathing: Even mild or intermittent symptoms deserve attention, as they can indicate that smoke is irritating your pet’s airways.
• Keep fresh water available: Staying hydrated supports your pet’s overall health and can help reduce irritation in the throat and nasal passages.

Being proactive during smoke events is always far easier on your pet than recovering from respiratory irritation after prolonged exposure.

Checking Air Quality Before Heading Outside

Before letting your pet outside for anything more than a quick bathroom break, it helps to check the current Air Quality Index for your area rather than judging conditions by sight alone. Smoke can look mild while particle levels are still unhealthy, especially in the early morning or late evening when smoke tends to settle closer to the ground in Central Oregon’s valleys. Treating any day rated unhealthy or worse as a stay-inside day for your pet is a simple habit that prevents a lot of avoidable exposure.

Protecting Your Home’s Indoor Air

Your home is only as smoke-free as the air you let into it. During active smoke events, avoid frying or broiling food, vacuuming, burning candles, or using a fireplace or wood stove, since all of these add extra particles to indoor air your pet is already breathing more of than usual. Setting up one well-ventilated room as a cleaner-air space, with a portable air cleaner running, gives sensitive pets, including birds, a place to retreat to on the smokiest days.

Recovery and What to Expect After Smoke Exposure

Pets do not always bounce back the moment the air clears. According to Oregon State University Extension Service, airway irritation from wildfire smoke can take several weeks to fully heal, even after visible smoke has cleared from the area. During this recovery window, keep exercise light, continue watching for coughing or labored breathing, and give your pet’s respiratory system time to settle before returning to a full activity schedule. Reintroducing hikes, trail runs, or long fetch sessions too quickly can aggravate airways that have not fully healed, so a gradual return to normal activity over one to two weeks is a reasonable approach for most pets. Pets with a history of heart or lung disease may need an even slower return to normal activity and closer monitoring from your veterinarian.

When to Seek Veterinary Care

Not every cough or sneeze during wildfire season requires an urgent visit, but some symptoms should never be ignored. If your dog or cat is breathing rapidly while at rest, struggling to breathe, making unusual sounds while inhaling or exhaling, or seems disoriented or unusually lethargic, those are signs that warrant prompt veterinary attention. Our urgent care services are available during business hours, 8 a.m. to 5 p.m., Monday through Friday, to address respiratory concerns before they become more serious, and our emergency veterinary care team is available for pets who develop severe breathing trouble outside those hours.

When a pet’s respiratory symptoms are persistent or unclear, chest X-rays and other diagnostic imaging can help our veterinarians assess lung condition and rule out complications from prolonged smoke exposure. It is also wise to revisit your emergency preparedness plan during wildfire season. If a fire moves close enough to require evacuation, having your pet’s essentials packed and ready can save critical time. Our blog on building a pet emergency evacuation kit is a helpful resource for Central Oregon families preparing for that possibility.
