I am sorry that you feel depressed over her. Thats not what puppies are supposted to do
they are supposted to make you happy
. Yorkies are a handful, but if you take the time and patience to work with her for a while she will turn into a great companion. Is this your first dog or is this your first yorkie? What are the hours that you have to work at the dentist office? If you dont think that you will be able to come home to let her outside or anything get a doggy sitter or send her to a doggy daycare.
