The games of Gimborn are games designed to entertain our furry friend, games where I can play alone and games where we can interact with them and increase the level of interaction. This ball is a game designed for interactive fun to be played outdoors. It was conceived and designed for the free time of medium and large dogs , with a bit wider chewing than small dogs, in fact it is created in super durable material , like all the games in the Gimborn line.
