Yesterday I got my 1st ever yorkie "Ivy" she came from a animal resecure and they got her from a puppy mill. I'ts hard to believe after all she has been though that she is as happy as she is. She is not housebroken so is it hard to break a yorkie that is 4 years old? Also are yorkie coats thin? I see that she had a hair cut but I don't know if it's from a bad diet or the grooming.I'm new to Yorkie Talk so as of yet I don't know how to put pictures on, when I do I'll put one on
