  The most respected, reputable Yorkie breeders do keep their pups to the age of 12 weeks and beyond to give them the best chance of proper imprinting and and development within the birth home with their mother and littermates.  By that time, they are usually much better equipped to face a change of home and leaving mom and their littermates and cope with the new life facing them than they are four weeks earlier.  As hypoglycemia can be a real problem in young, tiny dogs, you will have a month less of that to worry about.  Just look around on this website and see all of the information about why it is better to wait for 12 weeks and Google search terms about why it is better to wait to bring home toy breed puppies until 12 weeks and read about all of the thoughts by many, many experts and authorities on breeding and puppy care.  I know you will enjoy your Yorkie - they are wonderful dogs and so very intelligent and such good companions.  They are aces at being watchdogs!  But the best of all are the Yorkie greetings and kisses and cuddles.  And cute???  No cuter breed out there.  You will laugh each day at many delightful things they do.
