My dog Teddy also is a non nutered male (he was a show dog). He mates with Males and Females. Of course we don't let him because we don't want to bring any more puppies into this world. The only thing you can do is to seperate them. You will haev to neutre your puppy, that might help it out some. Sorry word is broken so I can't make sure all this is spelled right. But good luck, and make sure you want this puppy before you keep him. We don't need another dog a shelter. And if you can't keep him give him up now, puppies are easer to get adopted then an older dog. (in my oppionion)
