Pet dogs at risk of passive smoking

Background: Smoking is the main cause of oral, pharynx, esophagus and lung cancer in humans,which is explained by the direct contact of cigarette smoke with these structures. In addition,passive smokers can also be at risk. Passive smoking is the result of secondhand and thirdhandsmoke. Secondhand smoke is the inhalation of a mixture of smoke exhaled by a non-smoker, thistype of passive smoking may be associated with EST (Environmental tobacco smoke) for pets. Indogs, exposure occurs by inhalation of particles generated by cigarette combustion, transdermalabsorption and ingestion of residues through the animal’s fur, accidentally intoxicate cigarettebutts and lick the electric cigarette liquid; And it can cause many diseases and problems for petdogs. The aim of this study is to review the effects of smoking on pet dogs as passive smokers.Methods: Using the terms ‘passive smoking’, ‘pet’ and ‘dog’, articles were identified bysearching PubMed, Google Scholar, Science Direct, SID and Magiran. Then related articles wereidentified and included in this review.Results: Exposure to cigarette smoke causes DNA damage in dogs. In addition, nicotine incigarettes is a substance with high mutagenic and apoptotic potential and can cause angiomas andmalignant growths in pets. Also, amounts of nicotine in hair Dogs whose owners are smokers havebeen reported. In dogs exposed to cigarette smoke, macrophage and lymphocyte populations weresignificantly increased. The risk is seen more in breeds with short and medium length noses (Thisfact can be explained by the more effective filtration of inhaled air by dogs with a longer muzzle).high level of exposure to tobacco smoke is associated with a higher prevalence of atopic dermatitisin dogs.Conclusion: Pet dogs who live in the same environment with those smoking owners, are in highrisks of either direct, and/or indirect of nicotine toxicity. Both the exposure routes and doses ofETS in companion animals may be physiologically relevant to humans, and domestic dogs can beat risk of diseases in several ways. Because exposure may be via these multiple routes, pets mayserve as convenient models for exposure patterns. It is exposed to young children in the family. Inaddition, due to the similarities in the cause of cancer, dogs are known as a suitable model forunderstanding the types of human cancers. Epidemiological studies of companion animals mayhelp to evaluate the relationship between exposure to environmental tobacco smoke (ETS) andcancer risk in humans. Also, this issue requires further investigations in larger statistical populations and examination of multiple factors such as the number of smokers the pet owner hasin It takes days and its effect on Pat needs
