You may be wondering whether or not you should breed your dog. Here is some information. The summary is that if you want to do it right, and get healthy and happy puppies, it is very expensive and a lot of work. Many people have written several treatises on this subject including Ms Swedlow; this article compiles many similar points.
Remember that you are going to need a vet that is familiar with whelping dogs. This will be your best resource, as well as any long-time breeders that you know. Not all vets are knowlegeable about whelping so be sure to ask around and especially look for recommendations from local breeders that you may know.
