I got hold of pork bones (the knuckle part with a short stub of the hard bone+marrow) and gave one to Romeo last night. He went for the knuckle this time around and worked at it for almost 2 hours non-stop! I heard scraping sounds and did a little cheer. He also used his paws to hold the bone done, which is a complete breakthrough because he would NEVER touch his food with his hands before!! I checked his teeth immediately before and after giving him the bone. His back teeth looked cleaner and the stain on his fangs was lighter (one fang was almost white, the other had a bit of stain still). Yay! Maybe I should give him one of these every other day? Or every 2 days?
I wanted to leave the bone for another day but he'd already chomp off most of the knuckle bit!
