Pooches that grow up in a household with smokers are at a significantly greater risk of developing certain forms of cancer, according to Buckinghamshire Smokefree Support Service.
Indeed, dogs, cats and smaller pets are up to twice as likely to develop the disease compared to pets raised in non-smoking households.
Secondhand smoke can put pooches at risk of nose and lung cancers, making it paramount pets get enough time outdoors to enjoy the benefits of fresh air.
The organisation warned it is not just smoke that can impact on dogs' health as cigarettes lying around the home can also be chewed up, putting the animal at risk of poisoning.
Team leader at Bucks Smokefree Support Service Val Mills said: "As a pet owner I know how important pets can be to people. Some people may not realise that smoking around their pets will affect their health.
"Our service is here to help smokers who want to quit so they can make sure that their family and pets will not suffer from passive smoking related disease."
Although the disadvantages of passive smoking are well-documented in humans, there is less discussion of how secondhand smoke can impact on the wellbeing of pooches.
This latest warning may provide an added incentive to pet owners that smoke to kick the habit for good, with pooches often happy to follow their owners outdoors for a refreshing walk instead.
In fact, quitting cigarettes will not only be good for the health of both human and pet, but also helps to promote all round better wellbeing, not to mention plenty of savings on the price of smoking.
If you are a pet owner that smokes but want to quit the habit, why not look to a simple exercise routine with your pooch to help motivate you and keep on track with your goals?
You can then reward your pet with dog food and enjoy a wholesome homemade meal to refuel you from the workout.
