You said that Sadie was the first dog, is the largest dog and acts like the alpha. So, first, you should establish that she is the alpha by NOT giving them both equal attention. This could be confusing Sadie and Maggie, and Sadie probably still feels the need to establish her dominance. Pet Sadie first, feed her first, give her treats first, and give her special privileges. You should definitely still give Maggie her own time to be loved, but you need to make it clear to both dogs that Sadie is dominant. You should also establish that you are the alpha over both dogs, by not allowing them onto couches/beds, obedience training them, and start NILIF with both dogs. To prevent fights while you're gone, crate train both girls and keep them in their crates to sleep and stay in while unsupervised. It's much more safe for both dogs.

Being strict and setting limits for your dogs is hard, but they crave that. Dogs need to have a pack structure, and they need to know where they are in their "pack". A lot of people here have tons more experience, but I'm pretty sure this could be a good start good luck!
