Thank you all for your replies and advices. I think they are getting along a little bit better. I still don't know who is #2 but as long as I am #1 I'm happy, lol...
The name is growing on me and I probably will keep it.
It doesn't seem like they're going to kill each other any more.
I never had a girl and I had dogs all my life. Annie is 9m old and not spayed yet. The breeder told me she did'n have her first heat yet (Annie not the breeder

) . I'm going to spay her asap if I decide to have her but I don't know anything about heats and I'm really freaking out that it will happen before spaying. Is it bad ? What age do girls should have their first heat ?
I will appreciate any help with this matter.
Thank you in advance.
