How to Breed a Dog in Heat

If you're intentionally breeding your dog, and especially if you've paid a large stud fee, it's important that you watch your dog and know when she is going into heat. That is the only time a dog can conceive. Make sure that your dog is healthy and qualified before you breed her.


Step 1

Ensure that your dog is old enough to be bred. It can be dangerous for very young or very old dogs to get pregnant, and older dogs might not be able to conceive at all. Your dog should be at least 1 1/2 years old before you breed her.

Step 2

Research your dog's history. Any genetic disorders your dog or her bloodline carries could be passed on to her puppies. If she passes on dangerous disorders, it means unhealthy puppies that might live unhappy lives.

Step 3

Take your dog to the vet to have a check-up before breeding. Your dog should should be checked for a healthy heart and organs, and given any outstanding vaccinations to keep her protected from illness during her pregnancy.

Step 4

Watch for your dog to go into heat. Heat starts with a clear discharge from the vulva, moving to to a darker discharge as the heat goes on. After this discharge has been present for 10 to 14 days, your dog is ready to be bred. She will show that she's ready to breed by "flagging" her tail, or picking it up and moving it to the side.

Step 5

Take your dog to a male dog for breeding. Put the dogs together for 20 to 40 minutes and leave them together. Supervise this interaction to ensure that neither dog is injured during the process.
