I too have to agree with Liz. I also looked back on your posts and saw that you never mentioned getting Holly as a foster, but instead as a new member of your family. Dobermans are clingy/hyper/nosy/playful/loving/protective when NEED BE/aloof/and so much more. It's what I love about dobermans and what has drawn me toward them for life. It's very rare to find a dobie like Maggie who is for the most part quiet(hardly ever hear the dober whine at home). Maggie is still very clingy to me, ask anyone that I've been with with her. Holly needs something done with her maybe Agility or trick training
(IE: spin, nod your head, something of a challenge) or flyball. You don't have to show, all these can be trained in your backyard. Maggie learned Agility in my backyard and so did my min pin, Roxie. Remember to research before you get the breed. Dobermans do need a home with experienced people IMO. She's probably better off in a better home with experienced dobie people or someone that knows of a dog's high drive. I'll help you if you want, I sent you a PM. Be careful with your next dog, it's not always the breed that you can count on, but the dog itself. If your going to get a rescue, I'd suggest another adult but one with a background you can read and the foster parents can explain to you in detail about how the dog's lifestyle and energy level is.
