Well, see darlin', that is your problem right there! Did you think that a yorkie is a dog?
They are just furry children. I have had dogs my entire life. All sorts of dogs. But I learned real fast that Yorkies are a whole different story. They are very stubborn but very loving.
It sounds like you are very frustrated and I can understand, but it might help if you went and bought some books on Yorkies. To help you understand the breed a little more. They are notoriously hard to potty train. Scooby is 9 months old and still gives me a problem with it.
