Dogs serve in various roles, including search and rescue, medical diagnosis, and emotional support. They are also instrumental in cancer research. A recent study led by Purdue veterinarian Dr. Deborah Knapp explored the link between cigarette smoke exposure and bladder cancer in Scottish terriers. The study followed 120 Scotties over three years, revealing that those exposed to cigarette smoke were six times more likely to develop bladder cancer. Scottish terriers, genetically predisposed to bladder cancer, provide a valuable model for studying cancer in both dogs and humans.

The research team, including Marcia Dawson, analyzed the dogs’ environments and urine for nicotine metabolites to assess smoke exposure. Findings showed that even indirect exposure to smoke, such as from contaminated clothing, increased cancer risk. The study underscores the importance of minimizing smoke exposure for pets. Encouragingly, the study found no link between lawn chemicals and bladder cancer, likely due to pet owners taking precautions. The research was funded by the NIH, Scottish Terrier Club of America, and Purdue University.
