So cute
I have a 1.5 yr old cavapoo & cockapoo. They love the little squeaky toys that, esp my cockapoo. He likes to run around making them squeak. These ones are a little bit bigger than some of the others they have. I knew they would be. He still runs around with them, there’s just no squeaking. My husband loves peanut butter and jelly, I had to get them. They’re super cute! Made well.

I thought these are Cute My dogs didn't think so
These are cute and would work well for medium and larger dogs.  Not dogs under 25lbs.  The toys are to big for their little mouths and they can't get a hold of them to play with them.

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!
