Do Not Buy!!
I just opened these balls up and what a waste of money. They don't bounce at all. They are made not like how normal tennis balls are. They are filled with so much air on the inside to where they bust really easy. They also have so much glue on them and that even comes off really easy. I paid $ 25 and some change and what a waste. The first ball only lasted a few seconds it's already shredded and busted. I do have a dog with a strong mouth and that is why I picked these balls they seemed they were made to last. I have an Old English Bulldogge and the ball lasted only seconds. Threw the ball out to her she put it in her mouth and Poof not a ball anymore.DO NOT BUY AT ALL!!!

To easy to chew through.
These are already broken on the inside not safe for dogs. I am a groomer and ordered these to send home with my customers but the rubber in the middle is already broken and they can easily chew through the surface. It could ingest it and that isn’t safe.
Good for a dog that doesn’t chew

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
