There is very little you can do but wait until a month is up and take her to the vet.
You really need to educate yourself if you are going to be breeding dogs. I really wonder if you have done any of the research needed to breed in a responsible manner. Do you know what the common genetic problems of mini Dachshunds are? Have you researched their pedigrees to make sure their lines are free of them? Are they well behaved, healthy, and fine examples of the breed? Go to
American Kennel Club - akc.org and read their recommendations on breeding. Read some books. Successful Dog Breeding, by Chris Walkowicz, DMV is a good one to start with.
