A friend told me about this story. I have not been in the habit of writing about media news in this blog, but this story caught my attention and could be used to expound on nasal tumors in dogs.
Here is the story. Max, a Springer spaniel, passed away in Britain due to nasal cancer. He spent his days helping the police find drugs, specifically cocaine. I was saddened to hear of this ironic, dark twist. I am sorry, Max. I hope you are at peace.
Common cancers that affect the nasal sinus in dogs are squamous cell carcinoma, fibrosarcoma, melanoma, and rarely, transmissible venereal tumors.
Nasal cancer has been chalked up to several different carcinogens. Some of the most common airborne ones are in pesticides, herbicides, kerosene, fossil fuel emissions (from gas and diesel engines, industry and the like), and cigarette smoke. Here are some examples
2,4-D is a carcinogen found in over 1000 herbicides.
Nitrogen dioxide is a biggy too, leading to chronic lung disease, at least in humans. It is likely, but not proven yet, to cause nasal sinus disease too.
Oxygen-derived free radicals in smog are a likely (speculated) risk factor for DNA mutations leading to cancer.
Long-nosed dogs have a higher nasal cancer rate when inhaling second hand smoke particles. Short or medium nosed dogs have higher lung cancer rates due to the second hand smoke.
Asbestos exposure in dogs have higher rates of a cancer called mesothelioma, and people exposed to it get lung cancers.
So keep your dog away from these things as much as possible, and while you are at it, keep yourself away as well.
Best to all,
