Difficult to destroy. Bounce really high.
Style: Squeaker, Size: Small (2 Pack)
Bought as a gift for a friend's small dog who dismantles tennis balls. He loves them. I have many years of experience with the product (in a larger size) for my big dog. He always had one either in his mouth or near him. They are pretty much indestructible.

High quality, wish it was just a little smaller
Style: Squeaker, Size: Small (2 Pack)
Love these. My dogs would play ball all day if I let them. These are very durable and bouncy. Love that it’s washable. They would chew up the small “tennis” balls to pieces so I love that they can’t destroy these. My only criticism is I wish these were just a little smaller (like the size of the small Kong tennis balls). My dogs can carry it in their tiny mouths but they can’t get their mouth around it enough to chew it to get the squeaker to squeak, which is their favorite thing.

The perfect ball for a small to medium dog.
Style: Ultra, Size: Small (2 Pack)
My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball. A great entertainment value. This ball does not squeak.
