We have been using Orbee World balls all of Daisy's 5 years. She is a rambuncious yellow lab with jaws of steel. The new design ball in orange and white seems to be standing up better thatn the green and blue ones which fell apart immediately.
Great toy for a chewer by witch of the west from Boise, Id.10/30/2011
The ball has managed to withstand the jaws of Bear--part Rottweiler--and he loves it!
