You should not have any real big problems about fighting..it is common for one to be the boss (leader) and the other the follower.. as it stands for me my Daisy is 7 mths and she is the leader and My Sissy ..1yr.. is the follower.
But they both fight ,play, eat, sleep, together and best girlfriends...But when your female comes into her lady days (heat) you may want some advice than.. cause your male might ..ya know.... OOP'S.... LOL....
