DENVER/September 3, 2025 – Morris Animal Foundation announced the funding of a new study focused on learning more about the effects of wildfire smoke on dogs. The team, led by Dr. Sheryl Magzamen, Professor at Colorado State University, will leverage the data collected as part of the Golden Retriever Lifetime Study to investigate whether wildfire smoke exposure affects longevity and compare mortality data on dogs in the cohort with known data on regional wildfire smoke.
Wildfire smoke is a complex mixture of carbon monoxide, carbon dioxide, methane, volatile organic compounds (VOCs) and particulate matter (PM). The smallest of these particles can penetrate deep into the lungs and even enter the bloodstream. These pollutants come not just from burning vegetation but also from homes, cars and industrial materials consumed by flames.
When inhaled, these particles can irritate the respiratory tract, trigger inflammation and exacerbate pre-existing health problems. While there is a robust literature on smoke inhalation in animals, little is known about the long-term effects of wildfire smoke on animals.
Dr. Magzamen hopes that the findings of her study will lead to new state and federal recommendations for animals and become part of the veterinary school curriculum.
“Our beloved dogs share our world, including exposure to air pollution and wildfire smoke,” said Dr. Magzamen. “Our work could help inform recommendations for dog owners, and maybe even have farther-reaching impact on other pets, livestock, and even wildlife.”
“This is an incredibly exciting and meaningful use of Golden Retriever Lifetime Study data,” said Dr. Julia Labadie, Principal Investigator of the Golden Retriever Lifetime Study. “It’s a perfect example of how our long-term investment in gathering comprehensive health and environmental information on dogs can contribute to groundbreaking research. We’re proud to support work that not only advances our understanding of canine health, but could also shape broader public health guidance for animals affected by a changing environment.”
