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.

Bright color and tough skin both great

Color: Regular-Orange, Size: 2.5"(Medium)-12 Pack

These tennis-style balls are, as promised, much tougher and thicker-skinned than an ordinary tennis ball, being made as a fetching ball for dogs. I bought them as foot covers for the legs of walkers used by the elderly, a very popular use. They work extremely well to protect rugs and flooring, and to make a quiet gliding cover, easier for seniors to move smoothly without snags. The usual tennis balls used for this purpose wear out pretty quickly, but this ball was made to be repeatedly fetched and gnawed on by your Rottweiler, so it's a big improvement. You will need a good cutting tool to score in the crosswise slits where you insert the walker leg; it's too tough for your household scissors, but that's just the point, right? It's tough. Very much recommended!
