The German Pinscher is still a relatively rare breed within the United States and countries outside of Europe, so breeding the German Pinscher does require a bit of research since it may be difficult to locate other owners in your area. The good aspect of this limited availability of German Pinschers is that the breed has not been mishandled by backyard breeders and puppy mills or puppy farms, meaning that there are fewer chances that you will find a genetically inferior German Pinscher male, or female, even if you are not able to afford breeding into championship lines.
When planning to breed your female German Pinscher the first step is to have her completely tested for any health issues. This can include having her hips, eyes and joints tested as well as any other health concerns. Always ensure that her vaccinations and worming schedules are up to date and then take her to the vet for a general examination. Explain to the vet that you are planning to breed her so the vet can complete all the blood tests or other exams needed. Once your female has been cleared of any health issues the next step is to research and find a suitable dog. Typically, members of a Kennel Club or a German Pinscher Club is a good starting point, but still do some of your research online about the breeder and the kennel before making a decision. Always ask to see the dog and watch his or her interaction with the owner as well as the male's temperament. Temperament is often passed to offspring, so a well tempered male is just as important as his physical characteristics or history in the show ring.
Once you have selected the male, ask for a vet certificate or a health certificate for the male and plan to enter into a breeder's contract with the owner of the dog. This will include a stud fee as well as any charges for kenneling your female during while the breeding occurs. Liability for injury during breeding or kenneling as well as any exemptions should be clearly outlined in the contract. Many kennel owners of the male will also ask for the "pick of the litter" as part of the stud fee. This means that the dog's owner has first choice of the puppies that the female produces as part of the agreement.
After the female has been bred it is important to confirm pregnancy, usually at about day 25 after breeding. This can be done at the vets through an ultrasound. Don't rely on physical characteristics, females can go through false pregnancies and the only way to confirm this early is through the vet. At about 10 days later it is possible for a knowledgeable breeder to confirm pregnancy through palpitation of the abdomen; however this should not be done by someone that is inexperienced. Feeding the female correctly during the pregnancy is critical for both her health as well as the development of the puppies. Talk to your vet or work with the breeder to develop the most nutritionally balanced diet for her increased needs.
