The Cross Ball is now for 2 months in use and has everything unscathed. Of course, he is now countless imprints of small pointed Hundezähnchen but that's about it. The ball is prima suitable for ball and tugging. Only one point deduction, because in the case of tugging my dog properly applied force and me through the knobs on the toy hand hurts to long "to keep on the other hand". Maybe I'm a bit sensitive and thanks to the special shape of the ball I can access with 2 hands. Despite this reduces the fun on my side a little, that's why only 4 stars.
