Yorkies are high energy dogs, jumping, running around, bouncing off the walls is not uncommon. Dogs greet each other by sniffing faces or butts. When he is jumping he is probably trying to reach your level, so you can try bending down to greet him, talk to him, etc. When Chip jumps, I put my hand out kind of like a ceiling for him so he knows when he jumps and hits that ceiling he is supposed to stop. It is really something you should get under control as a preventative measure. My sister's yorkie used to jump so much he eventually injured his back and can no longer jump anymore but still tries.
