I would go to the library and grab any books they have on breeding. One expert I highly respected always insisted any book was better than none. What you need is beyond the scope of this site. You needed to do so sooner. Among other problems, it is usually accepted that a dog shouldn't be bred until it is 2 years old. I suggest either spaying her when this is all over, or doing some serious study. A good start is the breeding information at
American Kennel Club - akc.org If you are going to go ahead, Successful Dog Breeding, by Chris Walkowicz, DMV is a good book to start with.
