"My Australian Cattle Dog - aka Blue Heeler -loves herding these balls around the yard and shaking them and carrying them by the handle and beating them against the ground.
The ball does not deflate - but after just 3 or 4 times playing with it, the handle has teeth holes in it and will come off very soon. Too bad, cuz these balls are great toys but the balls are not nearly as rugged as my cowdog!"
