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.

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
