Why Dogs are the Best Workout Buddies: The Frisky Friends of Amanda Seyfried, Rosie Huntington-Whiteley, and More

Here’s the thing about having a dog: Shower-damp hair, polar vortex, and the siren call of the snooze button be damned, your day begins with a walk. And judging by the well-toned physique of Amanda Seyfried, a canine friend may be the best fitness buddy there is. Spotted in New York City with her Australian Shepherd, Finn, the actress made the case for the body-sculpting benefits of a year-round power walk. Over in balmy L.A., Rosie Huntington-Whiteley stays in shape thanks in part to regular hikes with her two dachshunds Dolly and Peggy, while blogger Hanneli Mustaparta took a day off from biking to explore the canyons with her rescue dog, Hillary Clinton. Not that every dog owner approaches their incidental workout with the same athletic fervor: Cocooned in a furry parka while out with her Maltese, Mr. Butler, the unfailingly chic Olivia Palermo showed that she, like any true New Yorker, hardly considers walking exercise.
