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

Puppy tested & approved

Color: 12 Tennis Ball

I ordered these squeaky tennis balls for my cocker spaniel. She absolutely loves these tennis balls with the squeakers in them! She plays with them all day, and chews on them frequently. We have not had any problems with her, breaking the tennis balls, which is generally the issue we have with her. The tennis ball fuzz stays on the ball very well, which is usually an issue with standard tennis balls, because my dog likes to peel off the yellow fuzz on all tennis balls. She has not been able to do that with these. I will definitely be buying these again , but will not need to anytime soon as these are extremely well built.
