Surviving a 8 month old heavy chewer
Color: Blue, Color: Blue
My dog is OK with it but doesn't like it as good as the whale indestructible toy I got her previously. She chews on it a little while and quits. She acts almost like it makes her nauseated. Idk though....
It gets very very sharp! Be careful grabbing it after they've chewed it.

Always great for keeping dogs out of trouble
My dogs love Nyla bones, no matter flavor. They simply love them. I replace them often when they start getting too old and chewed out.
