Jeffrey, welcome and congratulations!
Probably the best registration is through IALA at
http://www.ilainc.com/
If you are in the USA you can also register through the Continental Kennel Club.
It is much easier if your breeder has already registered, and then the breeder registers the litter and gives you papers...if not, you may have to work a bit to get everything in order for registration...but IALA is a fine organization and I am very happy with my membership.
Sure do hope you post pictures when you get a chance!
