Whether you\u2019re a smoker or a nonsmoker, if you\u2019re a pet parent, you\u2019ll want to know how secondhand and thirdhand smoke can affect your pet\u2019s health. Let\u2019s look at what we know about the effects of cigarette smoke on your dog.<\/p>\n\n\n\n
What is Secondhand and Thirdhand Smoke?<\/h2>\n\n\n\n![\"can](\"https:\/\/outwardhound.com\/furtropolis\/wp-content\/uploads\/2022\/06\/dog-secondhand-smoke-1024x536.jpg\")
<\/figure><\/div>\n\n\n\nWhen people inhale the smoke from tobacco products, this is firsthand smoke. They are inhaling it directly into their lungs.<\/p>\n\n\n\n
When they breathe the smoke back out and non-smokers or pets in the area inhale their exhaled smoke, that is secondhand smoke. Of course, we now know that firsthand smoke is associated with numerous negative health effects, and we know that secondhand smoke causes many problems for humans.<\/p>\n\n\n\n
Thirdhand smoke refers to dust, other smoke residues, and various particulates that are left behind when secondhand smoke lands on various surfaces in the environment. Clothes and pet bedding are left with a yellow color, they smell bad, and they feel grungy. <\/p>\n\n\n\n
Thirdhand smoke causes that contamination; but does it affect the health of people or pets who come into contact with it?<\/p>\n\n\n\n

<\/figure><\/div>\n\n\n\nA study conducted in 1998<\/a> by researchers at Colorado State University and published in the American Journal of Epidemiology found that dogs exposed to environmental tobacco smoke were at greater risk for nasal cancer<\/strong>.<\/p>\n\n\n\nInterestingly, the study also found that certain dog breeds were at greater risk. While any type of dog can be at risk if they are exposed to secondhand smoke, this study found that dog breeds with long noses were at an increased risk for nasal cancer as opposed to dog breeds with short and medium-length noses.<\/p>\n\n\n\n
This may be related to the ability of the dog\u2019s nasal cavity to trap carcinogens in the smoke. Long-nosed dogs trap more debris in their nasal passages and sinuses than short-nosed dogs.<\/p>\n\n\n\n
Short-nosed dogs<\/a>, however, do not escape the risks associated with secondhand smoke. They are at an increased risk for lung cancer. This is likely due to the fact that their shorter noses don\u2019t as effectively trap the smoke<\/a>, and the carcinogens then pass straight through to the lungs.<\/p>\n\n\n\nPassive smoking, anthracosis, and cancer<\/h3>\n\n\n\n![\"dog](\"https:\/\/outwardhound.com\/furtropolis\/wp-content\/uploads\/2022\/02\/oh_boston_2022-180-1024x683.jpg\")
<\/figure><\/div>\n\n\n\nA 2007 study<\/a> also found that dogs were affected by passive smoking. Whereas previous studies had involved the effects of active smoking by delivering smoke to the animal through a mask or similar device, this study looked specifically at secondhand smoke exposure in domestic dogs.<\/p>\n\n\n\nThe researchers found that certain white blood cells were elevated in the dogs exposed to cigarette smoke in homes where the owners smoke at least 20 cigarettes per day. <\/p>\n\n\n\n
Additionally, there were changes in the dogs\u2019 airways as a result of exposure to tobacco smoke. They also found anthracosis in immune system cells known as macrophages.<\/p>\n\n\n\n
Anthracosis means that there was carbon present in these cells. Anthracosis or smoke residue can cause respiratory problems like allergies, bronchitis, pneumonia, and an increased risk for malignant lymphoma. In humans, anthracosis is often seen in coal miners<\/a>. It is associated with numerous respiratory diseases including primary lung cancer.<\/p>\n\n\n\nThe 2007 study concluded that exposure to secondhand or thirdhand smoke puts pets at a higher risk for numerous cancers including nasal cancer, oral cancer, and lung cancer. Of course, such exposure to smoke may also have long-term effects such as heart disease and other chronic problems just like it does in humans.<\/p>\n\n\n\n
