Not indestructible, but the best I’ve found
Color: Onyx Black - Most Durable, Color: Onyx Black - Most Durable
This thing is unexpectedly heavy for its size. My 18 month old Giant Schnauzer is obsessed with fetch but destroys every ball she gets. The other brands marketed for extreme chewers tend to last about a day or two before they’re totally shredded. She’s had this one for about 2 weeks and it’s looking rough, but still holding together for the most part. I appreciate that as it comes apart it does so in little pieces rather than large chunks. While it’s far from indestructible, it’s the strongest I’ve found so far.

Great product!
Color: Onyx Black - Most Durable
Great product! Quickly became my Pit Princess's favorite toy! The size, weight, and material is perfect for a big dog. Now we have fetch ball that has proven itself to be worthy!

Belgian Malinois approved
Size: Large
This ball was the perfect choice for my 8 month old Belgian Malinois. Should last for years so far it has survived all her chewing needs. It’s the perfect size so I don’t have to worry about her swallowing it.

Good chew toy for an aggressive chewing dog
Size: Large
Well built for an aggressive chewing dog. I wouldn't say indescribable but it has lasted longer than all other chew toys he's had.
