Welcome to YT.  I also feed raw - but I opt for The Honest Kitchen freeze-dried raw.  I like the fact that it has vegetables in it (without grain).  I worry about too high a protein content for the senstive digestive systems.   
I don't know about raw pork for Yorkies.  I've always been told pork can be very dangerous for these little ones.
