The Dynamic Duo of Doggy Day Care. Want to double your pleasure and double your fun? Just take a look at Julius and Sly at Central Bark Doggy Day Care of Manitowoc. These two guys steal the show and our hearts with their playful antics. Whether they are playing with our other guests, the toys on the playground, or just throwing our Staff for a loop (or two!); they are a real joy to have with us. Having them both here since Fall of 2008 lifts our spirits as well as the other dogs’ too.
