Great toy but never received the replacement they offer.
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.

Very sustainable, cute and fun
My puppy enjoyed this toy! He goes around the house squeaking it and has not destroyed it yet.
