Oh Wish....nothing you do will change what has happened but I so agree that they shouldn't just get away with it. I know you and I know that you will do the right thing for Lucy....you have given her the best home and all the love anyone can give a pet. I am just so sorry that you have to have the end of her days be so horrific.
I know that I've seen pictures of her in the past...can you post one for us here?
