Planet Dog's interactive toy - the Mazee Labyrinth Ball.
Simply fill in a few dry treats, shake well down and give to the dog. He now has to move the ball until all the treats are out. Real occupation for the home. It is much heavier than a "normal" ball. In addition, the ball is transparent, so the dog can see the treats :-)
not suitable for chewing
currently only the green Mazee Ball is in stock.
