Wildfire smoke contains fine particulate matter (PM2.5) that can penetrate deep into the lungs, causing respiratory and cardiovascular issues. Vulnerable groups, such as children, older adults, and individuals with pre-existing conditions, are at higher risk. Pets, especially dogs, are also susceptible due to their outdoor activities and rapid breathing. Symptoms of smoke exposure in dogs include coughing, eye irritation, and difficulty breathing. Taking proactive steps to minimize exposure is crucial for everyone’s health.
