Monster Mutt is Brooklyn's original Doggie Daycare. Founded in 2001, Monster Mutt was the first doggie daycare in Brooklyn, and we continue to provide the best possible care for your dog. We believe that puppy play is the best exercise, and our indoor doggie playground provides plenty of space for the animals to get the mental stimulation, socialization, and all the play they needs. Your pup will come home happy and exhausted from each Monster Mutt visit.
