I agree with all it is a great under taking yorkies are high maitenance they require alot of time and i noticed you want a small baby please dont breed a small baby get a akc standard girl to start out with 5 to 6 pounds little furbabies having babies can be a nightmare if you want to become a breeder later make sure you buy for quality it will take more than 1000
to buy into nice lines and when you do get one please just dont breed to any male that you come across please do your home work you want to make sure this girl you are looking for is in a forever home with you
good luck in you search
