Smoking also harms pets

Researchers from Purdue University in the US have warned that dogs living in homes where smoking occurs are six times more likely to develop cancer.

Lead researcher Professor Deborah Knapp stated, "If pet owners who smoke reduce this habit, it could be a very positive development, especially for the health of their dogs."

The effects of secondhand smoke on animals had not been sufficiently researched until now. This new study sought to answer the question of whether cigarette smoke increases the risk of cancer in dogs.

The researchers tracked 120 Scottish Terriers, a breed known to be 20 times more likely to develop bladder cancer than other breeds.

The dogs were monitored for three years, during which time their health, diet, activities, and living environments were observed.

CANCER RATE HIGHER IN SECONDHAND SMOKER DOGS

The results revealed that dogs exposed to cigarette smoke were six times more likely to develop bladder cancer compared to dogs not exposed to smoke.

When a dog is exposed to cigarette smoke, its body absorbs the chemicals and later excretes them through the urinary tract. Over time, this can lead to cancer in the urinary tract.

This is not just due to inhalation. Dogs can also ingest these chemicals by licking clothing that has absorbed smoke.

Professor Knapp said, "If someone comes home after going to a smoky concert or party and their dog jumps into their lap for a cuddle, the dog can be exposed to particulate matter in the smoke through the person's clothing."

Just like humans, not all dogs exposed to secondhand smoke develop cancer, while some that are never exposed to cigarette smoke still develop it.

The researchers hope the findings will encourage smokers to quit entirely or to smoke away from their dogs.
