Pets verse baby!

Hello so I'm currently stuck. Me fiancé and I have had our dog for almost three years now and have had her since she was first allowed away from her mother. Well she's a pretty hyper dog. Not that she would ever purposely hurt the baby but my fiancé is concerned that she won't settle down. Now my father in law is currently living with us but is moving back up north at the end of February and has been begging to take her with him. But I can't find it in me to let her go. I know she would have a happy life up there but she's my baby too. I guess what I need is some success stories with you ladies and your animals and babies. Or advice on how you got them to adapt to the baby! Thank you!
