My vet has 3 yorkies she was telling me physically for the 6 almost 7 month old that all of his bloodwork is fine and as far as his temperment i dont know how or why my vet stated that but i am just here for some prof. help

i want to know everything that i should know from someone who has experienced breeding PERSONALLY. that is the reason i am here in my opinion the vet told me this only because of the high level of care that i provide and bears bloodlines however i know that these are not the only things that determine breed standard however i do not have the eye for that as these are my first yorkies i have a breeder that lives up the street from me however i do not like her breeding style and i am not going to ask her for advice i feel that yorkie talk is a good place because of some of the VERY EXPERIENCED breeders. i know that it is a lot of hard work but i am up for it. does anyone know of any know of any good breeders here in nc?
