Title: Jolly Ball doesn't hold interest
Review: My labrador retriever hasn't shown an interest in the 10" Jolly Pet Teaser Ball. I have tried to encourage her to play with it but no luck. She doesn't have any sort of obsession with balls or playing fetch, one or two throws and she's done, so possibly it just isn't her thing. It looks fun to me and I can certainly see where some dogs would find it fascinating.
