    Dogs love to get out and stretch their legs, which not only helps to keep them in shape, but enables them to keep the extra pounds off. Pet hiking has been popular recently, getting dogs off the sidewalk.

Three years ago, Denver resident Brittany Redding was stressed out, working 60 hours a week while studying in graduate school full-time. The only thing that helped was taking her four dogs hiking. “That’s when it hit me that I should do that as a job.” she says. After graduating in June 2016, she founded Take a Hike. Her company, like a number of others around the country, takes dogs to explore beyond the neighborhood.

Before taking on the tracks, Brittany meets with each dog and his or her owner to get a sense of the pet’s character. Then she schedules a meet-and-greet with other dogs that will join the hike to be sure to match their personalities. Each hiking is about two hours long and includes transportation to and from the track for around $70 per outing. “Hiking allows dogs lo meet new friends and explore new tracks, smells, and wildlife,” she explains.

Michael Mizenko thinks sending his pet, Ajax, on weekly hikes with Take a Hike has made Ajax a happier dog. Over the past two years, hiking has taught Ajax how to stay off pavement, be more social and remain calm in the car. “It has made him a flexible easygoing guy.” Michael says.
