My female puppy is in heat. How to prevent my male dog from breeding?

If you are unable to have one or both of the dogs spayed/neutered then you will have to be diligent about keeping them separated while the female is in heat. I would recommend keeping the female in the house and the male outside because if you leave the female outside there is a chance another male dog could mate her. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

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. Thanks for asking Petco Pet Education Center, formerly Petcoach!

You have some great questions! When Luna goes into heat, keep her and your make completely separate at all times until it passes. You are right that she shouldn’t be bred until closer to two years of age. No, they will not mate when she’s not in heat. Signs of heat include a swollen vulva, bleeding, and mounting behavior. A dog goes into heat once every six months, and it lasts 3-4 weeks. I hope this helps!

Great question! You are absolutely correct that it is too soon to breed Millie. You will need to keep them complete separate while she is in heat, which lasts three to four weeks. No contact at all, Keep them in separate rooms at all times, which means feeding them in these rooms. Take them out to potty separately. The only way to prevent them from mating is to keep them away from each other at all times. I hope this helps!

The only way is to separate them completely, obviously until she gets in heat she cannot get pregnant, but he could hurt her doing what he does. if you can't separate them you might consider having the male neutered early.

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.

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.
