I suggest you do a lot of research before picking a breeder (as a mautter of fact start with breed - you live in an apartment, what breed would fit your lifestyle). Also, for all you know your therapist could just be a run of the mill backyard breeder. Good breeders abide by certain guidelines and do proper health testing etc etc. A purebred dog is expensive and you want to know who your money is going to. If she is selling a mixed breed litter I would personally adopt from a shelter instead.

Also, what if she says no? I had to go through a whole interview process to adopt my 2nd dog from a reputable breeder. Sounds like you may be jumping the gun. Sorry if that sounds harsh, I don't mean it that way. Just passionate.
