How to prevent my male dog from mating with his mother in heat?

You need to keep them completely separated all day, everyday for three weeks until she is out of heat. The male can mount her quickly and breed her if they are together for even a short amount of time. You may want to send him to a friends house or her to a kennel to keep them from breeding. You are right she’s too young to have puppies. Thanks for using Petco Pet Education Center, formerly Petcoach to help you get answers to your veterinary questions.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! Unfortunately there is not much to do other than keeping them apart. This is not due to stress it is likely due to the hormones she is emitting and what Anakin is picking up on. Having her spayed should help with this problem but for now I would keep them separate if possible. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

If you have the two of them together while she is in heat, she may become pregnant. Even if they are from the same litter and are brother/sister, they will still breed if given the chance. Therefore, if you do not want them to breed, it would be best to either separate them completely while she's in heat, or have one or both of them "fixed." At 6 months old, your male dog can be neutered at any time. It would be best to wait until the female is out of heat, because the surgery is a bit more difficult to perform when the female is in heat as there is increased blood flow to the uterus.

All you can do is keep them separated - best to take one of them to another location (a family or fiend's house). I suggest you have them spayed/neutered (or at least one of them) or this will be an ongoing problem.

I would just keep them apart. He could suddenly become interested when she gets into a different part of her heat cycle and you may not be around to see it happen. With him being her father, you definitely don't want them to mate as their puppies could have a lot of health problems. I would probably keep them separated for a month to be extra safe. I hope this helps!

This is normal. If you don't want them to breed, you need to keep them separated. You may have to move one of the dogs to a friend or family member's house until the female is out of heat. I suggest you have them fixed as soon as possible. ( http://www.vospca.org/affordable-spay-neuter )

Yes, intercourse is possible between these two breeds, no matter age or size. The only way to prevent this is to keep them completely separate from each other, with no way to get to each other or to have at least one spayed or neutered.
