Please someone correct me if I'm wrong, Yorkies were also bred small because the king didn't want anyone to have a dog large enough to kill big animals, such as deer, because that was his food. Yorkies were then the peasants dogs. They had to be able to jump through a 7 inch hoop. Yorkies would sleep in the cupboards to keep the rats away. Sometimes they would be used as shop rags. Workers would wipe their dirty hands on the long coat. I remember reading this somewhere. I thought it was really interesting.
