It depends. Is the male becoming aggressive? If it is then something's wrong. Males are usually protective of the females and pups (depending on breed) so if it is acting aggressive towards the female then it will hurt the puppy's.

Do your research on the breed to determine what is the best way to protect not only the female and pups but the male because the female will attack the male if he try's to attack the puppy's.
