🚭 Cigarette Smoke & Pets: More Harmful Than You May Think
We know secondhand smoke is harmful to people—but our pets are exposed too, and because of their smaller size, close contact with floors and furniture, and grooming habits, their exposure can be significant.
Dogs and cats can be affected by both secondhand smoke (smoke they breathe from the air) and thirdhand smoke—the toxic residue that settles on furniture, carpeting, bedding, clothing, skin, and their own fur.
🐾 Potential health effects include:
- Chronic coughing, wheezing, and airway irritation
- Worsening of asthma and other respiratory disease
- Eye and nasal irritation
- Increased risk of certain cancers with long-term exposure
- Skin and coat contamination from smoke residue
Cats deserve special attention. Smoke particles settle onto their fur and are then swallowed during grooming, creating another route of exposure in addition to breathing contaminated air.
Dogs aren't immune either. Chronic exposure to to***co smoke has been associated with respiratory problems and an increased risk of certain cancers.
What about va**ng?
Va**ng around pets isn't considered a safe alternative. Aerosols can contain ni****ne and other chemicals, and ni****ne-containing liquids are particularly dangerous if a pet chews or ingests them.
🏡 The best way to protect your pets
Keep your home and vehicle completely smoke- and vape-free. Smoking in another room, opening a window, or using a fan doesn't eliminate exposure or the residue left behind.
If your pet lives with a smoker and develops a persistent cough, wheezing, nasal discharge, breathing changes, or recurrent eye or respiratory irritation, it's worth discussing with your veterinarian.
Our pets don't get to choose the air they breathe. Keeping their environment smoke-free is one more way we can protect their long-term health. ❤️🐾
