The Mating Ritual of Dogs

By Jerry Welsh


People that have kept dogs for a pet would know if the bitch is ready to be mated. Of course the swollen vulva and bloody discharge would be telltale signs but what would be more noticeable are the bitch's suitors that would try their luck to be accepted by the bitch. This condition occurs because dogs in the estrus stage would emit a smell that is not unlike a "come hither" signal to male dogs. Thus all the male dogs in the area would come a-visiting

Dogs are seen mating everywhere but the bitch would not be swayed easily by the attention of its suitors. From the male dogs that surround the bitch only one will be allowed to mount. When the bitch is ready, it will allow the male to mount by holding her tail to one side giving easy access to her vulva. This action is known as flagging. The penis will penetrate the vulva when the male dog mounts the bitch from behind. After penetration the male dog would commonly swing one leg over the bitch back so that the dogs will be stuck end to end.

Dog owners that have not seen the mating act of dogs may panic given that the dogs may appear to be highly stressed or act as if they are in pain. It is natural for mating dogs to be stuck end to end and owners must never try to separate them. This part of the mating act is known as the Tie Phenomenon or the mating tie.

A dog's penis, unlike human penis, can penetrate the vulva even if it not stiff because it has a bone called baculum that holds it rigid. Once the penis has penetrated the vulva, the bulbus glandis located at the base of the penis will swell. The erectile tissue will cause the tie as it traps the penis inside the vagina until the male's ejaculation is finished. The bulbus glandis will return to its normal size after the dog has finished ejaculating. After ejaculation the dogs will be able to separate.

This kind of mating ensures that the bitch will get impregnated because leakage of sperm and the prostatic fluid will be prevented. Because it is common for dogs in heat to be surrounded by male dogs, a smaller dog that was chosen by the female can be ousted by bigger and more aggressive dogs even before the mating is finished but the mating tie ensures that the mating will not be interrupted.
