IHeartSnS has given you some good info, but even still what a sad situation. Please don't give up on this pup. He is still young, and many yorkies aren't fully potty trained until even past one year old. Also I'm sure he doesn't understand that you are his owner now. Perhaps you can try to bond with him in the meantime while your gf is still in town. Do things together with all three of you. Make it fun stuff so he'll like being with you. Get him to like you first, then focus more on training a little later. If he doesn't like or respect you, training will be almost impossible. The best way to train yorkies are through positive training methods, not through fear and punishment. Please no spanking. All you need, if you really want to physically tell him no, a firm but small tap with one or two fingers on the hind quarters is more than enough for him to get the message.

It would really be a shame if he had to go through another rehome. It doesn't sound like the original owners really spoiled him like a yorkie should be spoiled, esp since the husband didn't respect him, that's just so sad.

If you have more questions please ask us. I think rehome should be the absolute last resort. Good luck.
