It's such a Yorkie thing! I love it! That running in the air, wiggling all over, trying to get some tongue anywhere near the new arrival. cracks me up.
Not sure how you can handle it with people that don't like it. My oldest son (living at home) complained when we first got Shelby. I told him he would have to get used to it. Now he comes home from work and lays on the floor and just lets her have her way with him

Once she is "done" she will stop, then he can wash up and have some peace.
People that don't like it don't visit here that often and when they do Shelby sort of ignores them. Their loss.
