Our industry leading Tuff Balls®, now comes with a squeaker! Tuff Ball Squeaks are the perfect toy for a dog that loves a squeaker. Tuff Balls are made with thick, natural virgin rubber to provide durability and better bounce. They use polyester felt instead of the standard wool felt used in a competition ball, because polyester felt won't wear down your dog's teeth. Tuff Balls are the first tennis balls made specifically for dogs, with millions sold and a name you can trust.
