Man’s best friend

Evanston resident Paul Chasnoff and his springer spaniel Elio regard each other with obvious affection during a recent training session at the Segal Visitors Center at Northwestern University. A retired marketing and IT manager, Chasnoff walks Elio several hours a day. “We train all the time. If you have a dog, you’re always training the dog, because you’re giving constant cues,” he says. “You just might not be training them the behavior you want.”
