I'm going to email them PRETENDING I'm interested in one of their Yorkies that looks like hes not purebred. And see what she says about the genes and stuff. I will pretend I'm like really dumb too.
EDIT: Not to mention they are selling breeds like Bull Terriers who have the same type of personality of pit bull.
ie:They cant be left alone with other dogs. So they need lots of reaserch wich I doubt any of them did. Not to mention they are also a store! I cant find theyre e mail though
