Very Durable Ball
Pattern Name: Cage Ball, Size: Large - 4 Inch / 8.5 oz
This ball has held up to regular puppy chewing for 3 months now. At first I was worried my retriever would get her mouth stuck in it, but it hasn't been a problem since she has gotten bigger. Supervision required for smaller pups.
One thing to note is that the ball was shipped with a strong rubber smell, but that has gone away with use and washing. Super easy to clean!
It is a heavier ball making it bounce well and it doesn't damage the walls.
Super durable. She's been chewing on it every day and there is no damage to it at all. The scratches, holes, or pieces missing. It's stayed intact for months!

Good ball, but not really for super chewers
Pattern Name: Ball, Size: Large - 3 Inch / 12 oz
This ball is tough...my (foster) dog is tougher. It is a heavy rubber ball, but my Staffordshire bull terrier is able to destroy these balls within about a couple of hours. We never let him chew on these unmonitored. If you have a moderate chewer, this is probably ok for your dog; for any super chewers, you might want to pass.
We first bought one of these balls when we learned our foster dog (fresh out of the shelter) had heartworms. We knew we had to keep him occupied somehow, and it is by far his favorite toy (he loves the doughnut-shaped toy as well). We bought MANY of these during his heartworm treatment. Now that he is done with his treatment we won't buy any more of these. They are expensive for what they are. And just be aware that the lifetime warranty only applies to material or manufacturing flaws...not the actual toughness of the product.

LOUD, bouncy, and perfect for small dogs
My dog is a massive squeaky toy fan. She's also pretty aggressive with her squeaky toys and they usually don't last more than a month. This one is perfect for her - durable, noisy and bouncy. She loves it. The package comes with six but I only have her one and it's lasted nearly a month which is a record because none of her other silicone squeaky toys have lasted this long. It's perfect for her small mouth too. If you live in a flat with thin walls you might want to enforce a curfew with this toy or reserve it for outdoors because it is LOUD. Wear ear protection if you get migraines like me LMAO

Great squeaky toy!
Best squeaky toy for our 18 pound 'puppy.' Great for indoor or outdoor use and he hasn't punctured them yet!

Good quality, lotsa fun
Not easy to find a sturdy toy for a minipoodle that loves to play rough with his toy. He has not been able to break this into pieces and that feels reassuring that I don't have to worry about little pieces and choking. These things bounce funny and my boy loves playing with it
