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.

Squeaks break immediately

Color: 12 Tennis Ball

Squeaks break almost immediately, even with very light chewing. Some are so badly made that the squeaks break after one or two squeezes. Get Kong balls instead.

Nice balls but arrived with a bad chemical smell

Color: 12 Tennis Ball

Wonderful Product!!! The balls themselves are amazing and the squeaker in them my dog loves. I am giving them only a three star because they arrived and they SMELL like chemicals so bad!!! I was afraid to give it to my dog so i washed one out and put it up hoping the chemical smell will go away. This not good for a dog as unknown chemicals can make them really sick. Whatever amazon is spraying on their stuff it's not good
