Went through the Kong products like they were nothing.
Came across this product in a little pet supply store and read about the guarantee and was sold. We bought the small and then went back for the large when they had it in stock. This ball has made it 4 years now without any signs of true damage. It does great no matter where we go and my destructo lab has yet to take down her huck ball.
Keep making them my friends, they are great items! Oh and if you need a test dog, send them our way. Layla will be happy to obligue.
