Well, hello, stranger. Welcome back! Huey is the only yorkie I have had, and he is very cuddly but on his own terms. He is a very happy guy who is always ready to play and when he gets the zoomies, he is hilarious to watch running his "zoomie path" through the house. He is a good sleeper, but also likes to quietly play with his toys in the middle of the night, because we will awaken to the entire contents of his toy box in the bed with us. He also is quite skittish at times and looks like a flea the way he hops around to avoid being caught, like when he hears the water running in the tub or when he sees a hairbrush coming his way
I think that a yorkie, like any other living being, is gonna be somewhat shaped by his/her early life experiences, and each has a distinct personality.
Looking forward to hearing updates on your search!
