I buy 4 of these every month for my dog. He won’t go anywhere without this ball. He sleeps with it, swims with it, goes to the vet and carries it around in his mouth to show off. It’s borderline a problem. My dog is a large breed and plays hard so I do purchase often because the strings unravel and the ball itself is foam so breaks down into little pieces after a few days of playing. I love that it is fragile on his teeth and jaw. We can play catch indoors because it is soft.

Great for indoor fetch! Definitely hit the windows and the TV a couple times without any worry. Super fun, my dog loves it!
