I had an excited peer once. It was driving me nuts. He was a hyper dog. Initially I tried low key, soothing greetings (as I know many people who have had success with this method) but, no matter how calm I was, he was really excited! The peeing was endless. So finally what I would do whenever I came home was walk right past him without saying a word or acknowledging him, walk out the back door with him, sit down in a chair I kept outside and, then would excitedly love him up. He quickly learned that outside in front of that chair is where he needed to be and, where we said hello. He was so determined to get to that spot that he didn't have time to stop and, be excited enough to pee. Then he could pee all he wanted with out driving me crazy.
There are so many ways to deal with emotional pee. (ha! Sorry, sounds hilarious!)
Puppy's have so much life ahead of them and, this beautiful girl seems to have had so much time taken from her in a hard way. If you can offer her the love and, quality of life she's been missing all this time, I say go for it. I'll mail you a swiffer mop to help keep you sane
