Get fit and have fun by working out with your pup.
By Alison Goldman
"Dogs really enjoy going for a run because they spend so much of their life in your backyard," says Sundance. The first time you go jogging together, start slowly. Medium-size dogs with a lean build, deep chest, and long muzzle—like Border Collies and Weimaraners—are best-suited for running. Gauge how well your dog handles a half-mile run, then build up by quarter-mile increments. Dogs typically enjoy being in front of you—if yours starts to slow or fall to your side or behind you it's time for a break. Look out for heavy panting, pale gums, or foaming at the mouth, which are signs he's tired or overheated. And after every outing, check his pads for scratches.
