Secondhand Smoke and Canine Cancer

Not all dogs will develop cancers or health problems from exposure to secondhand smoke; however, research shows that the chances of developing cancer are greater for dogs living in smoking environments compared to dogs from non-smoking environments. Long-nosed dogs have an increased risk compared to short- and medium-length-nosed dogs. The more smokers in your household, the higher your dog's risk of developing smoking-related cancers, as well as lung infections, respiratory problems, asthma, and other dog health problems.
