PET owners are being urged to stub it out as part of a new stop smoking drive.
The Doncaster Stop Smoking Service has targeted veterinary surgeries, pet shops and grooming parlours with posters to highlight the risks of second-hand smoke to animals.
It is the first time that the service has aimed a campaign at smokers who are pet owners, and staff are hoping that it will help steer people towards a healthier lifestyle for themselves and their pets.
There is evidence that dogs, cats, and other pets are adversely affected by passive smoke.
Maryanne Wylde, stop smoking specialist, said: “We hope these posters will make smokers stop and think about the damage they might be doing to their beloved pets.”
