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.

Better than tennis balls for dogs

Color: Orange, Size: Large

My trainer said better for my German Shepherds than tennis balls. They seem to like them, and they last a lot longer than regular tennis balls. We started using regular tennis balls as the dog ones broke first time out. They still managed to break the regular tennis balls also, just not a quickly. Once I found out tennis balls were not good on their teeth I bought these. The rubber ones are great.
