You're welcome
When initially emailing a breeder, you don't have to ask too many questions. You just want to know if he/she has what you want. Ask if they have any current litters, or if they will have any litters before spring. Tell them you are interested in a female, and ask how much they usually sell their females for. Make sure to tell them a little bit about yourself, like the fact that you are a stay-at-home mom.
Once they email you back, if they have anyone that you might like, you can start asking them more personal questions. Ask how long they have been breeder, if they have the parent's on site, how many litters they have a year, where were the puppies raised and how were they socialized, what are the pedigrees of the puppies, and if they have a health guarentee. A good breeder will be able to answer all of those questions, and will be glad you asked.
Hope that helps!
