Every pooch needs a dog treat ball like this one! It promotes thinking and helps reduce boredom, which in turn puts a stop to destructive chewing. It has a durable rubber construction that is slightly springy. Put the treats through the hole with flaps on the top and then give to your dog. Your dog will roll the ball around and will have to chew it in order to get the treats/dry food to fall through the maze inside the ball which will cause the treats/dry food to eventually fall out the bottom.Easily clean the ball by running warm tap water through the hole to wash the inside.
