The Mating Procedure
Most canine couples are capable of carrying out a breeding under a watchful breeder's eye. However, you may need to help the dogs into position if one or both have difficulty. A bitch that is ready to be bred will allow the male to sniff and lick her vulva as she holds her tail up and out of the way. Ideally, the male will then mount the bitch from behind and proceed to penetrate the vulva with his penis.
In just a few moments, two glands on either side of the penis will begin to swell inside of the vulva, producing a clamping response from the bitch that results in a tie. During the tie, the majority of the sperm are delivered into the canal. The male may choose to remain on top of the bitch, or slightly off to her side. He may also twist around so the two are facing in opposite directions. The important thing is to calmly keep them from pulling on one another so neither dog's genitals are injured. The tie typically lasts from ten to thirty minutes, and then the swelling subsides and the dogs can separate.
