National Pet Carbon Monoxide (CO) Safety Day

National Pet Carbon Monoxide (CO) Safety Day is observed annually on September 17. In 2026, this date falls on a Thursday. This day serves as a vital reminder for pet owners to learn about the dangers of carbon monoxide, a colorless, odorless gas that can seriously harm or kill pets. Many people are unaware that their furry companions are even more vulnerable to CO poisoning than humans, making education and prevention essential.

History of National Pet Carbon Monoxide (CO) Safety Day

National Pet Carbon Monoxide (CO) Safety Day was founded in 2020 by Kidde, a leading manufacturer of fire and carbon monoxide safety products. The company established the day to raise awareness about the silent threat of carbon monoxide and to encourage pet owners to take proactive safety measures. Each year on September 17, the day focuses on educating the public about the risks CO poses to pets and how to prevent poisoning incidents.

The need for such a day became clear as thousands of pets in the United States are exposed to carbon monoxide poisoning annually. Because CO is invisible and odorless, it can accumulate in homes from common appliances like heaters, stoves, and generators without any warning. Pet owners often mistake early symptoms of CO poisoning for other illnesses, leading to delays in treatment. The day aims to change that by spreading knowledge and encouraging the installation of CO detectors.

Why is National Pet Carbon Monoxide (CO) Safety Day important?

Pets are at higher risk from carbon monoxide poisoning than humans due to their smaller size and tendency to spend more time in enclosed spaces where CO levels can build up. Symptoms in pets—such as lethargy, difficulty breathing, vomiting, and confusion—are frequently misinterpreted as other health issues, which can delay critical care. Without prompt treatment, CO poisoning can lead to severe tissue damage, coma, or death.

Raising awareness about this invisible danger saves lives. By understanding the sources of CO and recognizing the signs of poisoning, pet owners can act quickly in an emergency. National Pet Carbon Monoxide (CO) Safety Day also highlights the importance of simple preventive measures, such as installing CO alarms and maintaining fuel-burning appliances.

• Carbon monoxide is produced by the incomplete combustion of gas, oil, wood, or coal.
• Common household sources include heaters, stoves, fireplaces, generators, and cars.
• Pets show symptoms like nausea, lethargy, uncoordinated movement, and seizures.
• CO binds to hemoglobin in the blood, preventing oxygen from reaching organs.
• Early detection through alarms can prevent poisoning incidents.

How to Celebrate National Pet Carbon Monoxide (CO) Safety Day

Observing this day means taking concrete steps to protect your pets from carbon monoxide. Start by ensuring your home has working CO alarms on every floor, especially near sleeping areas and where your pets spend most of their time. Test alarms weekly and replace batteries as needed. Have your fuel-burning appliances—such as furnaces, water heaters, and stoves—inspected and serviced by a professional at least once a year.

Education is another key part of the observance. Learn the signs of CO poisoning in pets and share that information with fellow pet owners. Create an emergency plan that includes your veterinarian’s contact information and a clear route to fresh air. Spread the word on social media or in your community to help protect as many animals as possible.

• Install CO detectors on each level of your home.
• Schedule annual maintenance for all fuel-burning appliances.
• Familiarize yourself with pet-specific CO poisoning symptoms.
• Keep your pet’s microchip information up to date.
• Share safety tips with friends, family, and online networks.
