American Bulldogs

I quickly need to find a good home for my 2 year old American Bulldog. I adopted her from the shelter at 6 weeks young. She has attacked my 10 year old Rotti for the last time over a bone. She is a great dog just needs to be the only dog. I am having a terrible time finding a home for her and can't bear the thought of putting her in a shelter. We live in Delaware. Any help would be greatly appreciated!!!
