My boy eats breast of lamb and ribs. I don't give him pork as it tends to make him sick but lamb is a definite winner and a couple of sides of ribs are very cheap from the butcher.
I feed lamb bones, more ribs than shanks and chicken carcus, i have found beef to be too hard and same as above all ny dogs seem to be sick after pork.
Just ordered some 150 lamb bones from landywoods bet my dogues cant wait til thurs. It makes me beam too though seeing them happily chew gets rids of the bad breath too.
