Healthy Hound Playground, Reston

With its large windows, high ceilings, and 6,200 square feet of frolicking space, Healthy Hound Playground strives to convince pups that they're always outdoors. The facility's play areas are divided into three cage-free sections where dogs of similar size, activity level, and political leanings can mingle together. Humans enrich their play during daycare sessions with one-on-one activities such as Frisbee fetch or a 2-mile run. At night, pooches can hunker down on elevated cots inside private Canine Cottages. All of them get tucked in beneath cozy fleece blankets, but various boarding packages boast different amenities, from cuddle time to email updates for pet owners.
