The Red Rover doggy daycare in South Carolina separates its canine guests into two groups depending on the dogs' energy levels: Side A is for the chillaxed, introverted doggos, while Side B is for the more active, extroverted pups.
And there's no denying which group is which! Just one glance at the dogs in action and it's a dead giveaway — no guesswork needed. Until the end of the day, that is, when the hyper Side B dogs run out of batteries and morph into Side A dogs for a good long nap.
