well the first "red" flag I see is the LINK to her site....she advertises Teacup yorkies! No reputable breeder uses the word teacup!! That is a selling tactic of byb's or puppy mills...
I would NOT buy from her again!! Her attitude when you called her..is not the typical attitude of a GOOD breeder!
Good Breeders WANT to know how their babies are doing...and are NEVER annoyed to hear from their buyers.
Don't feel bad....I've been educated since I joined YT myself....and I won't make those same mistakes again in the future.
