Stop Smoking – For Your Health and Your Pets’ Health
You don’t need us to tell you the
harm that smoking can do to your body
, or the risks posed to children and others from
. But perhaps you’re unaware of the harm it can be doing to your pets. Because pets
share our environments
, they also share our
– including tobacco smoke.
Dogs living in homes with smokers have significantly higher levels of cotinine (a breakdown product of nicotine) in their blood, indicating
exposure to nicotine
through secondhand smok
found that environmental exposure to tobacco smoke resulted in an increased risk of cancer of the nasal cavity and sinuses of dogs, particularly those with
(such as collies, greyhounds and many other popular breeds); and the more packs the smoker smoked, the higher the dog’s risk of cancer.
This is likely because their longer nasal passages accumulate the cancer-causing toxins. A
found that dogs with short- and medium-length noses were more than twice as likely to develop lung cancer if a smoker lived in the home,
most likely because shorter-length nasal passages don’t accumulate the cancer-causing toxins, allowing them to enter the dog’s lungs instead.
Pet cats living in smoking households are
more than twice as likely
to develop malignant lymphoma (a type of cancer) compared to cats in nonsmoking households. The risk increased with the duration and amount of exposure, and cats with five or more years of exposure to secondhand smoke were more than three times as likely to develop malignant lymphoma.
Have you ever had anyone tell you that your clothes smell like smoke? Well, it’s not the just the smell that can linger – it’s the potential toxins, too. If you smell smoke on your pet, consider the toxins that may be on your pet’s fur. Chances are, they’re ingesting them when they lick the toxins off during grooming.
Birds’ respiratory systems are particularly susceptible to airborne contaminants. Significantly higher
concentrations of cotinine
were found in the blood of birds living in smoking households compared to birds living in nonsmoking households.
Birds with exposure to secondhand smoke can develop pneumonia, lung cancer, and problems with their eyes, skin, heart and fertility.
Smoking outside the home reduces the concentration of environmental tobacco smoke in the house, but doesn’t eliminate it. A
found that environmental tobacco levels in homes of smokers who smoked outdoors were still five to seven times higher than in households of nonsmokers.
And it’s not just the secondhand smoke that poses a risk for your pets: discarded cigarette butts or other tobacco products left within reach of pets can cause gastrointestinal problems or even
if your pet finds and eats them.

Kick the Habit, for You and Your Pets
If you smoke, please consider quitting – if not for your health, then for your family’s health and your pets’ health. Looking for inspiration or resources to help you make the commitment to quit? The U.S. Centers for Disease Control and Prevention (CDC) have great
for you and the American Cancer Society also provides resource and sponsors the
Great American Smokeout
on the third Thursday of November.
