Unfortunately I ended up being very disappointed with this purchase, after about two weeks of use, it just stopped performing. Not sure what happened but it just stopped releasing the ball and I don't know why, it had no flexibility left to it. I'm not doing a very good job of trying to explain why it quit working but suffice it to say, it became useless after a couple of weeks. Broke my neighbors dog's heart, lol.

Great ball!

Color: Ultra, Size: Large

Our puppy loves this ball. It has held up well so far, it’s about 2 weeks now of large breed pup play. It’s been outside for the last week, rain or shine, still in working order. Not as big as I thought it would be though. No squeak, bounces well. Thick rubber like material, that can be depressed when biting down.
