Chili the Belgian shepherd is a dog whose nose could save millions of dollars, protect hundreds of jobs and potentially ensure the future of Canada's burgeoning greenhouse pepper industry. The industry, which is worth $275 million and is concentrated in Leamington, outside Windsor, Ont., was devastated last year by a tiny invasive pest called the pepper weevil.The weevils burrow into bell peppers on the vine to feed and lay eggs. The peppers eventually drop to the ground and die. For about three hours each day, Heide leads Chili through different sections of the sprawling NatureFresh complex. They first concentrate on the loading docks and massive distribution centre where weevils can get in by hitching a ride on equipment and supplies, such as rented wooden pallets that could have been used on infected farms
