Why Do Dogs Get Stuck After Mating?

This is known as “tying up”.  This happens near the conclusion of normal mating and can last up to an hour or so.  Usually the male turns around and the dogs stand tail to tail.  It occurs because the female has a sphincter muscle at the junction between the vagina and the vestibule called the cingulum or constrictor vestibularis.  This sphincter contracts proximal to the swollen bulbus glandis of the male’s penis.  Do not attempt to separate the dogs during this time, as it can cause injury.   It is thought that this tying up helps fertilisation.

THey are mating. Your female dog is more than likely pregnant now. You should take her to the vets. Don't let them do this anymore. Both dogs can get really hurt if one of them move too much or you pull them apart.

Because they are mating, meaning they are making puppies and it's that certain year too when they know it's right to mate.

My dog never got stuck does tht mean she has 2 try again?

My yorkie and my grandmaw's yorkie are mating.. We only took him over for 5 hours.. When they were mating he acted like after that he did'nt act like he did'nt want ne thing else to do with her. So is there a pretty good chance that she is pregnet. Or should I bring him back over.. ??
