KONG Sport Balls (3Pk) Medium

My border collie usually loses interest in toys fast, but these extra-thick rubber walls hold up to her hardest chomping and she still goes nuts every time I wind up to throw. Even left outside in the yard for a week, they haven't cracked or split like the cheap balls we've had before.

My labrador has destroyed every tennis ball we've ever bought, but these extra-thick rubber walls have survived three weeks of daily fetch in the yard so far. She goes absolutely nuts chasing them, and the bounce is perfect for a good game.
