I’ve reported several times in the past (1) that dogs have keen senses of smell and science has proven that their noses can accurately detect both mold infestations and human cancers. So, it shocked me when studyfinds.org reported (2) that they can not only sniff out human cancers, but their “posterior sniffing” of each other can actually give them a cancer called Canine Transmissible Venereal Tumor. What is it in a canine behind that would transfer cancer cells to a dog’s respiratory system?
Volatile Organic Compounds (VOC’s) have been isolated from fungi, cancer tumor cells and feces. About 6,000,000 dogs are diagnosed with cancer annually. Since dogs can accurately sniff out cancer, I have to wonder if colon cancers are common in dogs. Dogs not only inhale each other’s posteriors (male dogs much more commonly that female dogs) but they also taste each other’s posteriors, and this may explain the transfer of cancer cells. Remember also that dog foods have been found highly contaminated with fungal mycotoxins and science has proven that several fungal mycotoxins can cause cancer in animals.
They say that you can’t teach an old dog new tricks, but perhaps we have finally found a new use for our old masks!
