Are You Unknowingly Feeding Your Pet Carcinogens?
Dr. Turesky is able to remove the hair shaft, cut it, break it open and do chemical analysis on it using mass spectrometry methods. He first tried this on his own dogs to see if he could detect exposure to a potential carcinogen in their fur.
He wasn't really expecting to get a positive result because his dogs don't eat grilled steaks or hamburgers. So he was stunned to find that they did indeed have the carcinogen in their fur.
After the experiment with his dogs, Dr. Turesky set up a collaboration with the University of Minnesota's veterinary college to conduct a small pilot study of about 15 canines. Thirteen of those 15 dogs tested positive for the carcinogen in their fur.
