Behavior with another pet (dog)

I have a short-haired 2yr old female. Darcy has been great. We have a fenced in backyard (40 yds) and squirrels and birds). Our vet told us to get another pet for Darcy to play with when she was about 8 mos. We got what seems to be a mix b/n terrier and boxer female. They got along great, until my wife got pregnant. Mattie then seemed to try to exert dominance over Darcy. Darcy would have none of it. They have gotten into several scraps. Big ones. No blood though. We've tried so many things. Our vet tried several as well. Now that we have a baby in the house, Darcy's (and Mattie's) world got smaller. We can't have them growling (which is what they do) all the time around our baby. So....they have become outside dogs. We have made adjustments (heated dog house, etc.) They can't come in without Darcy growling at Mattie and Mattie towering over Darcy. If they are alone, they love each other. They sleep indoors at night and snuggle. What is up? It seems that when we are around, they growl and fight, when we aren't, they are fine. Darcy sits by the glass door and whines a lot. It's breaking my heart. I don't want to have to give them up. Help......
