Pooch Hotel, Norwalk

Outfitted with spas and treadmills, Pooch Hotels are nearly the same as human accommodations, with one key difference: your dog might get a tummy-rub with their turndown service. These venues were all designed by dog-lovers whose main priority was canine comfort, regardless of the length of each guest's stay.

Dogs on daycare visits, for example, are sorted by size and temperament before entering one of multiple play areas. Monitored by human "Pack Leaders," they socialize amidst toys, treats, and wading pools at select locations, or run outside if the weather and facilities permit. Those who have booked a room for the night can relax in a private suite, outfitted with a glass door rather than bars. These range from standard to presidential and even palace suites—rooms outfitted with luxury bedding and flat-screen televisions tuned to dog-friendly programming. Customers might also schedule a spa appointment for their pooch, choosing from services such as baths, "pawdicures," and even facials.

The hotels pursue peace of mind for owners as actively as they pamper their dogs. Certain locations have installed web cameras in the play areas and suites, enabling people to check in on their pets and guilt them about the time they napped instead of writing a postcard. Staff remain on-hand at all times to welcome newcomers and care for already-snoozing pups.
