Everyone has made really good points.
I wanted to add, that training a dog, especially a Yorkie takes time and patience. Punishing is the WRONG approach. They do not learn the right way by punishing (that is hitting, yelling and especially putting their face into the potty - please do not ever do that again).
The correct way to train is positive praise for GOOD potty and a small treat to back it up. I use Peanut Butter Chips from the baking isle, they are small and effective. Yorkies are very smart and they are eager to please, but most of all, they love their Good Boy treats
...again, hitting and putting their faces into potty accidents are NOT successful approaches, these things will ONLY put fear of the owners into them, and that is not end result most owners want. You want your Yorkie to learn the things that make you happy
so those are the things you need to focus only. Ignore bad behaviors and reward good ones - progress will happen faster than you think.
And as others have stated, if you can not properly changes your training methods, please visit our Rescue Section, as you will definitely be able to find a family that will do the job correctly.
Best Wishes
