The sport of herding sheep with stock dogs is not going away any time soon. This month, the Crook & Whistle Stock Dog Trials competed for their 21st year in Wisconsin. It attracted more competitors than in years past. John Wentz organizes the competition. When he’s not helping at a stock dog trial, he’s raising the sheep to help train handlers and their dogs for the sport. He tells us about the tight-knit community of competitors and what it takes to be a champion. Wentz also says that need for stock dogs may grow as people start grazing sheep on solar farms.
