Cancer screening: ‘Man’s best friend’ takes on a whole new meaning


It certainly ranks as one of Canada’s more curious health exports–a cancer screening service performed by dogs, half of them rescued, all of the mutts.

It’s all happening in the small (55,000 residents) Quebec city of Aylmer and is the brainchild of Glenn Ferguson, a former advertising graphic designer who saw a BBC documentary about similar operations in the U.K. and California five years ago.

They have since added two more dogs with two more due to arrive in the not-to-distant future.

All are part-beagle combined with various other breeds of hounds.

The Fergusons and their dogs have now screened over 20,000 U.S. firefighters and members of their families from 50 firefighters unions, enough success for Donna, whose salary was helping to bankroll the operation, to quit her graphic designer job last November to work full time on the project.

Many in the scientific community remain sceptical, but the Fergusons estimate their dogs are 60 to 70 per cent accurate in their screening and have posted recent studies on dogs’ abilities to detect cancer on their website (
