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.

So far, so good!
Finally! A toy my 55 pound, 18 month old puppy hasn’t destroyed in minutes, and one she actually LOVES playing with. It has a really cool bounce and she loves chasing it and it’s easy for her to grab and run back to me with. So glad it wasn’t another waste of money. My only suggestions are to make this in a fun color other than black, and to make other just as strong toys besides a donut (she already has 2 other donuts from different companies which surprisingly have weathered her jaws) and add a squeaker to one of these ultra strong toys. More than chasing the ball, she loves squeaking!

10/10 Great game changer for aggressive chewers
After a scary experience where our Doberman ingested part of a toy and needed emergency surgery, we had to get rid of all plush toys and small balls in our house. Replacing everything felt overwhelming. This ball has been fantastic. It’s truly built for aggressive chewers and holds up incredibly well. It’s perfect for fetch, strong enough for tug-of-war, and the bounce is excellent, which keeps our dog fully engaged during self-play when he’s entertaining himself. That unpredictable bounce makes it exciting without being unsafe. Most importantly, it gives us peace of mind. No shredding, no chunks coming off, no felt cover and constant worry about ingestion. Since having to replace all of his previous toys and balls, this one has stood out as the best by far. If you have a large, powerful dog—especially a Doberman—or a dog who destroys toys quickly, this is a must-have. Durable, safe, and genuinely fun. 10/10, highly recommend.
