Soild
Size: Medium
The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it.
The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Perfect Dog Toys!
Color: Regular Ball Multi-color, Size: Medium
My dogs absolutely love these! My problem was I have two (of 4) that play ball. One is 15#'s and the other is 40#'s. So, I couldn't decide on the size. I decided on the medium, and they have been perfect. My smaller dog has a bit of a problem holding on to the ball, but he can get his mouth around it. For my larger dog, it's not so small I'm worried about her swallowing it. So, the size was perfect!
These are thick enough neither of my tough chewers have been able to penetrate the balls, but soft enough they can easily pick them up. They have that squeak that drives my dogs nuts. The little faces on them are cute. We have spent hours playing ball with our two dogs with these balls. They absolutely love them. My small dog brings them to me constantly. Although. of the 7, it's a miracle if we know where 2 are at any given time. I actually remembered to write the review when I spotted 3 of them at the same time.
My ONLY small complaint is the rubber plus dog slobber and rolling under furniture means these balls can pick up a lot of dust and hair. I have to rinse them occasionally as they can get rather gross. Luckily, they are very easy to clean with water and dry with a paper towel. Then they are as good as new! We can get right back to playing.
I highly recommend these balls as you will spend hours enjoying watching your dogs play fetch. We absolutely play ball in the house, as watching the mayhem of two dogs chase the ball down hallways and across rooms in incredibly entertaining!
