Dogs love these cute toys
Color: 4 Colors For M/L 3.1", Size: Large
My Boston terriers love these squeaking toys just the right size, they like playing together with these , the only thing is my dogs kill the squeakers pretty fast they figured out how to do that. Would have given a five if the squeaker lasted longer, but still a nice product.

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. 🤣
