Instructions
Take both dogs to be examined by a vet; both animals should be in perfect health before breeding. You do not want any genetic problems, birth defects or illnesses in the pups. The vet should check for eye, heart and joint problems. Be sure to let them know of your intent to breed. Also consider temperament, as no animal that has aggressive or obsessive tendencies should be bred.
Wait for the female dog to come into heat. Although many females come into heat for the first time between 6-12 months, it is best to wait at least two years before breeding them. The average heat cycle lasts three weeks, but your dog is most likely to be fertile between days 7-14. You will know that she is in heat because she will have vaginal bleeding and rub herself against objects. Keep her confined during the entire heat except for the actual mating to prevent her from encountering other male dogs.
Look for vaginal discharge that is straw- or wheat-colored; this signifies that the female dog is at her most fertile. At this point, place an emergency muzzle on her and allow the male access. Muzzling her will keep her from snapping at the male and ruining his "amorous intent."
Place both dogs in the room where the mating is supposed to take place. The dogs will take some time getting to know each other before mating. Do not allow the male to mount the female until she indicates readiness to mate by whisking her tail to the side and standing still.
Allow the dogs to complete the mating process uninterrupted and intervene if necessary. Some inexperienced males may mount the wrong end or be unable to penetrate the female; guide him as needed. If the female is nervous or irritable, speak to her in soothing tones.
Repeat the mating process the next day just to be sure.
How to Cross Long- & Short-Haired Dachshunds
It is possible for any two breeds of dogs to be mated, so long as the size difference isn't too great. Crossing long- and short-haired dachschunds is entirely possible and not very difficult; however, before allowing the dogs to mate you need to be sure that you will be able to handle the costs associated with breeding and provide every single puppy with a good home. If you are breeding for profit, recognize that mixed breeds are often less valued than pure breeds. You might consider pairing with an experienced breeder for the first litter.
