If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.

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.
