Aggression issues

I have a 3 year old female Labrador retriever. Last year, she was stolen out of my yard for a month. I got her back and she is now aggressive towards other dogs (except the ones in our home). We are in an apartment complex now, and having trouble keeping her away from other dogs in the complex. I have tried walking her at all times of the day, and we always see at least one other dog. She is always leashed of course, but she lunges and barks at the other dogs. It’s so upsetting and definitely an inconvenience for other renters. We simply can’t avoid other dogs. We are stuck in this lease for at least another 10 months but this situation is stressful for everyone especially her. She definitely feels threatened no matter how far away the other dog is. If she even catches a whiff of another dog without seeing them she begins to growl. She is the sweetest girl, and I want to help her. I just overall don’t know how to fix this. I tried rewarding calm behavior, but can’t ever get to that point because she is never calm. She sense another dog before I do. I don’t know what happened to her while she was gone, but clearly it was something bad considering her new behavior. I used to take her everywhere and she could be around any dog no problem. Has anyone dealt with this and been able to find a solution? Any trainers have different suggestions?
