Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.

Best dog toy ever
So good I bought another. My dog is obsessed with this. The only downfall is after she has chewed it a bit l, it becomes sharp to open

Fun and durable toy
Lots of fun for this crazy guy! He pounces on it, chases it and has so much fun. The confusion on his face is so funny. He usually gets bored fast, however this ball keeps him quite entertained. The ball holds a charge for a few playtimes so that is also a plus!

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
