Another one of our favourite toys here at the daycare is the Teaser Ball, made by Jolly Ball. We started off with a big one for the big dogs to play with and eventually got a smaller one for the little pups. It has been a big hit with many of the dogs here at the daycare.
We don't find many of them obssessed with the ball inside but for some reason they seem to enjoy carrying it around and chasing it. And sometimes chewing on it. The outer ball is a very hard plastic so it can take quite a lot of abuse.
