Not even close to "virtually indestructible" as described.
Within an hour of receiving this K9 Chew Stick, our 55lb Staffordshire Terrier began chewing pieces off the top of toy. Initially, we were happy to see that our dog enjoyed the chew toy, and it appeared to be durable. For the high cost of this toy, it is very disappointing that pieces can start coming off that quickly. Luckily, our dog wasn't swallowing the pieces, which can easily lodge in their intestines. If your dog is NOT an aggressive/determined chewer or they are happy with chewing for very short periods of time, this toy might be okay for them.

Really great ball
Our yo German Shepard loves this ball. She can get hold of it on all sides. Really a tough toy. Hasn’t chewed it up. Loves to toss it herself.

Brilliant Ball
This is my dog, Sunnie, favorite toy besides a mostly flat basketball. The toy has some weight to it, but it isn’t too heavy for her (she’s a husky mix, maybe 25lbs and is 6-months old). The ball is the perfect size for medium and large dogs, has a lot of bounce, and is easy for Sunnie to pick up with her mouth because the open holes. The quality is good, worth more than it costs. It’s easy to clean. I’d buy many more, but this ball seems like it’ll last a lifetime.

Almost indestructible would recommend
I have owned the Monster K9 Indestructible Ball for one and a half years, and it has proven to be the most durable ball I have used for my German Shepherd. Out of all the balls we have tried, this one has lasted the longest under frequent, heavy chewing. Although my dog has finally managed to chew through it, I remain very satisfied with the product’s overall longevity and performance.
I would definitely recommend purchasing this ball to other dog owners, especially those with strong chewers. It has provided exceptional play value over an extended period of time.
One area for improvement is the warranty process. While the product advertising mentions a free replacement, there is no clear guidance on how to submit a claim, and I found it difficult to locate that information. Providing straightforward instructions for warranty claims would enhance the overall customer experience.
Overall, this is a high-quality, long-lasting ball that I would recommend, particularly for large or powerful dogs.
