THE chances of developing cancer are greater for dogs living in smoking environments than for those in non-smoking ones, according to research. As the number of smokers in a household increases, so does the risk of smoking-related cancers, as well as lung infections, respiratory problems, asthma and other dog health problems.
Dogs with longer snouts have an increased risk for nose cancer compared to medium and short nosed dogs, as they have a greater surface area that is exposed to carcinogens and a larger area for them to accumulate.
Dogs that get nasal cancer usually do not survive for more than a year.
Short and medium nosed dogs are more prone to lung cancer because their shorter nasal passage is not as effective at accumulating the inhaled second hand smoke carcinogens, so more reach the lungs.
