Girlfriend is going to get an abortion unless I debark my dog?

My girlfriend and I have been living together for about 2 years. She's hated my dog from day one and has been nagging me to debark him because his barking is too loud when she is watching tv. A few days ago we just found out she is pregnant and she is threatening to get an abortion if I don't debark my dog. I'm a pro-life Catholic and I believe abortion is murder, but I also can't just mutilate my pet either. Please help, I know she's serious and that she will go through with the abortion. Should I let my girlfriend abort our baby or should I get my dog debarked?
