I'm so sorry you are going through this, first off, thank you for giving Lola a loving home
and my best advise would be getting some training going as soon as possible! My two females have taken to fighting here lately, it can be very frustrating! What I've done to help work with the situation, when the girls get into a fight after I separate them I make them lay beside each other until they are completely calm ... I am top dog in our home so when I put them next to each other I stand right there and I won't let them move until they are completely relaxed. I always always always keep all of them separated, mine are all crate trained and feel strongly that it is the safest place for them when I can't be at home with them. Training and consistency are your best bet to get things back on track. taking a training class with both dogs will help but like advised above having a behaviorist come into your home would be excellent, that way they understand that what they are learning happens at home too. My first bulldog was the perfect "class" dog but at home she was a total brat more my fault than anything, I needed to learn to be the "Pack Leader" and didn't have the right composer at home and she fed off of it. With the 3 I have now, they have total respect for me and I have learned to always be consistent with everything in our home. My girls still get into a few fights but each time the same thing happens and they go for long periods of perfect companionship. I just have 1 girl (Madison) who doesn't understand how to play and she is the one who starts the fights and it is always when the other 2 are playing.
I hope things get better and please keep us updated.
