Its great to know you are putting effort into this and looking for help - God knows, the Doberman breed is not like others.
Though I wonder about how much time she is getting outside. At one year of age, she should be waaaay beyond pooping in the house. That should only happen when ill or in the case of a very very long stretch inside...which ideally, shouldnt happen.
Also, how much outside play time/exercise/running does she get? This is so incredibly important and cannot be exchanged in any way, for anything less. Well, actually it can be. But you dont want to make that trade lol.
Well I haven't had her the whole time... My mother in law bought her (She is a know it all) and basically "trained" her with yelling and chasing her. Mischa was about 9 months old when my MIL decided that she had created a monster, that was food aggressive, dog aggressive, would not come to you for anything in the world, she ate everything and my MIL couldn't get her potty trained... because she didn't try. She started jumping the fence and chasing cars. She would steal things off of the table and my MIL would basically just chase her around the house screaming at her until my MIL gave up.
My MIL was going to put her down because... and I quote "Well if I can't get her to mind then no one else will be able to." LMAO When this dog was about 4 months old she could be running through the house and since I always had treats I could show my command for sit and she would slide to a stop wherever she was. I got yelled at because she didn't want her dog trained with treats, and I wasn't allowed to give her anymore. She said "If I have to give a dog a treat to get it to do what I want then it isn't a very good dog." Mischa is VERY smart and wanted to learn so bad she could taste it but she has hit a wall in her "training" because of my MILs "skills". Anyway I told her I would take her, and she let me... I figure she is waiting for me to fail so she can rub it in. I have had her for about 3 months now and she is like a roller coaster, I would finally think that I was getting through to her then she would just go back to how she was at my MILs. She would shoot the gap going out the door, like the rest of my dogs I started making her sit before and after she came in or out of the door. This worked for a while but then it is like she said... hmmm nope don't gotta. Well my husband was home and when his friend walked in the door she shot the gap and since she wouldn't come to you because she thought she was in trouble... she got hit by a car. I worked at a vet clinic at the time, and THANK GOD the vet trusted me enough to let me take her to the clinic and told me what to give her over the phone... while he was driving to the clinic. He lives about 45 minutes away. She almost died, and at first we thought it broke her jaw... but the xrays showed that it didn't. She is fine now, she came back full force! Since then she doesn't want to have anything to do with the road but cars... not scared one bit if they are in the driveway.
A friend told me about this site because I was at my last resort. (I didn't know anything like this existed before) After she ate through her kennel... pulled the carpet off my stairs, broke a window and went to the neighbors to chase the horses my husband said we were getting rid of her. Well I can only ignore him for so long. So I am here now trying to absorb as much as possible so I don't have to get rid of her. I understood when I took her that it was going to be a BIG challenge, I am not expecting miracles but I know she is smart and somewhere deep down she wants to learn, the hardest part is her getting over her previous "training".
I used to take her for a 2 mile jog/walk almost everyday but if not we would play fetch and stuff like that outside after I got off work until it was about dark. BUT now that I am cracking down we have a 2 mile walk/jog in the morning and at about 6 We are taking a walk around the block, then playing when we get back both times. Up until she started fighting my dad's female Boxer she was outside on nice days all day while I was at work. Now she is in a Kennel when I am gone, until I can find my dad's dog a home or he finally shows up to get her. He is another story that I won't even get into.
I know this is REALLY long but I thought I should properly explain myself (or try to), because it does look like I have let her go for a year without teaching her anything if I don't. I have put a small dent in her bad habits but she has so many of them sometimes it is hard to see the light at the end of the tunnel.
Sorry for the novel.
