Pet's info: Dog | Japanese Spitz | Female | unspayed | 7 months and 24 days old

Hi. Tnx for your valuable willingness to help for goodness sake. I have two 6-month male/female puppies (Japanese Spitz Cross), the female got into the heat, I'm searching for the instructions and "to do"s, though it would be awesome to be recommended a sourse and very kind of you, but my important questions are about what to do about the kids being together an all, within the cycle and after (being adult and all) is it safe to keep them together?

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!
