Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

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.
