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.
