I am so sorry you were not mentored. Sometimes it is too hard if you are in a different state or too far away in driving miles. You really need to find someone close to you, so you can visit at their home and actually see how they groom and etc.. Also easier if you are closer and to answer those questions that pop up. Handling classes are usually up to you to sign up and attend. You can usually find classes through your local dog club. Is there a yorkie club near you? They are very helpful too - to make friends and have some help. I hope things go better for you this next time. Good luck.
