Pet owners breed dogs for different reasons, like preserving their bloodline and creating adorable puppies to keep or adopt.
However, dog breeding is challenging due to many scientific and environmental factors.
Whether you intend to breed your female dog or not, understanding a dog’s mating process is important for any responsible owner.
In this article, we answer questions related to one particular aspect of dog breeding — how ties correlate to female dog pregnancy.
What Are the Chances of My Dog Getting Pregnant After a Tie?
The chances of your dog getting pregnant after one mating session and tie are higher than you might think. Dogs do not tie every time they mate, and tying does not guarantee a pregnancy. However, about 40% of female dogs become pregnant after their first mating experience.

If you’re interested in dog breeding, a high chance of female dog pregnancy seems straightforward, but dog ties during mating make the topic much more nuanced.
There are also methods to prevent pregnancy after your dog mates if you do not want to breed your dog.

What is a Tie in Dog Breeding?
If you are a new dog owner or breeder, you may not know what a tie is and why it is a crucial dog-mating factor.
A copulatory tie in dog breeding means two dogs lock together during mating due to the expansion of the male’s bulbs glands. This organ connects or “ties” the female and male together.
Ties are a standard step in the dog mating process. Here’s a brief overview of canine breeding:
- Mounting: When the female dog is ready, she alerts the male dog, and he mounts her.
- Locating the Vulva: If the male dog is inexperienced, he may need help finding the female dog’s vulva.
- Ejaculating: The male dog releases sperm and other fluids.
- Copulatory Tie: The two dogs lock together from their rear ends.
- Coming Out: The dogs release their tie, and the mating process ends.
Why Do Dogs Tie When Mating?
Without much knowledge of the dog mating process, it may be confusing or even nerve-wracking when you see two dogs tied. However, ties are not dangerous. It is a natural part of the breeding process.
The copulatory tie keeps the male and female together during and after ejaculation. Staying together increases the chance of pregnancy because it keeps the sperm inside the female, helping it fertilize her eggs.
Since female dogs only go into heat every six months, copulatory ties ensure a better chance of conception.
How Long Does a Tie Last in Dogs?
Many breeders consider the copulatory tie preferable and part of a successful mating process. The duration of a tie depends on the length of the mating session.
When the dog’s tie, the male dog steps over the female dog, and the connection lasts between 5 -10 minutes in this back-to-back position. In its entirety, the mating process lasts anywhere from 10 minutes to one hour.
Do More Ties Mean More Puppies?
If dogs mate and tie multiple times, there is no guarantee for more puppies. Larger litter sizes depend on a variety of factors. Breed size is the most common determinant of litter size. Larger breeds produce larger litters because they have more space to carry puppies.

Another factor that impacts litter size is age. Each dog breed reaches sexual maturity at different ages. On average, smaller breeds mature quicker than larger breeds.
Once male dogs reach sexual maturity, they can mate at any time. If they remain healthy, male dogs can stay fertile and sexually active into their elder years.
How Many Times Can Dogs Tie?
For breeding purposes, typically, dogs need one tie for female impregnation while mating.
Further, there are no limits on the number of times a male dog mates or ties. Male dogs may breed multiple times a day if given the opportunity. If permitted by the owner, it is not uncommon for a male and female dog to tie several times a day.
How Can I Get My Dog Unstuck After Mating?
Watching your dogs stuck to one another might seem jarring at first. However, you should never forcefully separate tied dogs.
Even if you are trying to prevent pregnancy, forcing tied dogs apart creates stress for the dogs and may hurt them in the process.
Dogs that breed for the first time could take longer to separate, but don’t panic. Your dog may pick up on your worry and become nervous. If your dog seems anxious while tied, soothe them with gentle pats or ear scratches. They will eventually detach once the process ends and they relax enough.
How Can I Prevent Pregnancy for My Dog?
You have many dog sterilization options, but pet owners typically opt to spay or neuter their dogs to prevent pregnancy and offspring.
When vets spay a female dog, they remove the ovaries, Fallopian tubes, and uterus. The dog no longer has a heat cycle, and she’s unable to reproduce.

If your dog is already pregnant, vets can still perform the procedure as long as it is early in the pregnancy. However, spaying a pregnant dog is more invasive and increases the risk of complications.
When vets neuter a male dog, they remove its testes, meaning he cannot reproduce. Neutering also eliminates instinctual breeding behaviors.
Spaying and neutering are excellent options if you do not want to breed your dog because they help reduce pet overpopulation.
