At the risk of sounding flippant -do bears sh^t in the forest ??
Seriouly butchk9, unless your male has been neutered or the female is infertile, you'll very very likely have puppies in about 63 odd days from now, so if that's not what you want, now's the time to do something about it. Good luck !!!
Not only will they mate....they will mate or try to 24/7.... the male will not leave the poor bitch alone....... Please seperate them for her sanity and safety.
