Falls apart within minutes!
I’m a real human and person (sad I have to say that) who bought these stupid balls for my dog because tennis balls are EXPENSIVE. She chewed on them only a few times and the balls split in half into two hemispheres right away. Plus, she could rip the felt off the entire ball in less than an hour. Absolutely terrible and I truly threw money away because I threw away the original packaging and so I can’t get my money back! Very disappointing and sad :-(. Turns out that Play Again sports sells used tennis balls for $0.35 each. Sorry, Amazon. I’m getting my tennis balls from them from now on 😠

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
