Keeps her busy!
Color: Medium size (5.9")
Our Molly loves this. Only thing is that it is a little too big for our Maltipoo, but she still tries to keep up with it.

Tough
Color: Medium size (5.9")
So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

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. 🤣

These are long lasting, durable dog toys. My dogs love the squeak sound.
