Place in treats or kibble from the top and bottom flaps, and then as your dog plays, the holes on the sides dispense the treats gradually. Rubber-like material keeps hardwood floors and fragile furniture from getting scratched, while staying durable to doggy jaws. This is not a chew toy. Supervise your dog while playing.
