After more than 10 visits to the meat shop. This morning I tried talking to the butcher(wrong spelling), he took out some raw beef bone from the refri for me to choose!!!! Here they are. And they are suprising cheap (total US$0.60). I was told that it is the back of the cow. I will freeze it for a few days before use. ANy comment about the bones? good for teech cleaning and recreational use? Tks Need to hide that from my gf. Forgive her, there is a rumor in HK that a dog will bite human after it eats blood.
