6 DOG TENNIS BALLS 2packs of 3

I have a cocker spaniel, it took her about 1 minute to brake, not chew up by tearing, just by closing her mouth the pressure split the balls into three pieces under the felt cover, that was two out of six, took the third to the field with the dog, through ball on grass, dog brought it back, looked like a small rugby ball.

Dog likes these.
