Brilliant Dog Proof Tennis Balls
Bought theses after finding one on a dog walk and discovering that my dog couldn't burst or damage it after weeks of trying. He normally takes about 10 seconds to puncture any other tennis ball and then not much longer to start devouring it (but some Head ones did last a week or so each). None of these Wilson ones are punctured yet after 3 weeks (approx 8 weeks for the one we found)
