It’s is a very durable toy. But not indestructible. My dog loves the ball and it did last 4 months which is much longer than any of his other toys. I emailed the company to see if they honored their one time replacement policy for Amazon orders. I was told they do and was told I was shipped a replacement. But we never received it. We’ve ordered plenty from Amazon before and after this so I don’t know where the hold up would of happened but here we are. I did email the company back and told them that I didn’t receive the replacement and asked if they could verify my address….but they haven’t responded. Just sucks. Would of been great if I actually got the replacement!

My HEAVY chewers favorite ball

It's dense and has some weight to it, can definitely get good distance when throwing and it bounces a long way. It's soft enough for my dog to chew on but tough enough that even with her destroying every toy I get her she looses these before ever tearing into them. About softball size.

Safe

I normally don't write reviews but these products deserve the effort! I bought 4 different black toys from this Brand and all are still intact after 6 months heavy usage by 2 aggressive chewers (a Belg Malinois & black Lab), fantastic products and unlike so many other brands promising to be indestructible, these are the first toys that were not eaten within a month. No more visits to Vet to pay for Xrays after digesting plastic or rubber from badly made toys. Highly recommended.
