Please note, this says beef bones. Beef, knuckle, bones. For dogs to chew on. When you get them, if they are gristly, try and cut off most of it because of belly full of gristle can cause diarrhea in sensitive house dogs.
Attempts show what a knucklebone looks like when you get it, and then what it looks like after a day or three of gnawing by a 60 pound dog.
LOts of life left in the chewed on bone. I won’t take that away from Ajax probably for another few days.
I have published other more thorough articles on knucklebones, including some downloads, posted at Drjohnson.com, as well as drjohnson.net.
