Extremely sturdy. I had a larger one for my chocolate lab. Got it when she was 9 mo. old, she was a chewer. She died a year ogo at 13. Ball is still here. She tried hard to get the inner ball out. Kept her happy for long time. Now I got the smaller one for my 9 mo. old Corgi. Perfect for her. She puts it on her nose and walks around. Great toy for dogs.

Very sturdy ball. Chester loves it and it’s taken some serious play!!

This ball is the one that my pup plays with every day. I waited to see if it stood up to being flung about on hard floors. Apart from chasing it and rolling it about, he likes to fling it about for the noise. He likes to bring it over when I'm sitting at my desk to play footie. I'm careful with that as he can get his teeth into the holes to carry it about and I don't want him to get a tooth caught. When we get back from walks and he still has some pent up energy, he races around the yard with the ball in his mouth. So far, two months in, the ball is not showing any cracks in the plastic or chewing marks in the edges of the holes. Very good product.

I bought this ball for my dog when he was about a year old. He chewed through everything else besides a big Kong bone. We couldn't throw the bone to play fetch because you didn't know which way it would bounce!Our pet store suggested this product because it had apparently been made for horses, therefore, he wouldn't be able to destroy it. He had a large one and this size.He did manage to take them apart but it took him 7 years to do it.He loves it.

My labradoodle loves this ball. It keeps him entertained for ages.
