Great toy my dog loves!
Color: 12 Tennis Ball
My dachshund, Winston, loves these balls because they squeak and of coarse it’s a ball. Only thing is he is destructive and the squeaker doesn’t last long but by far his favorite toy.

Balls need to squeak out of the box
Color: 12 Tennis Ball
The squeaky ball lights up the faces of my dog shelter furiends, they love to fetch and chew the ball to make it squeaky. I have been buying these balls for about a year now. They don’t last long with some of the dogs, but the joy is worth the price. Lately some of the balls do not squeak right out of the box but many of the balls are fine. Returning the box doesn’t make sense because I used some already so I thought I would comment, dropping one star so far.

Nicer than I expected
Color: 12 Tennis Ball
Much more sturdy than other "squeaky" balls of this type. I love that they have an internal or covered squeaker, so I don't have to worry about my dog chewing it and swallowing a plastic squeaker. But ... what I find as a plus, my dog sees as a minus, since one of his favorite thing is to chew a ball until it stops squeaking. They come in a plastic net bag, which is very handy for storage also.
