I don't think they were completely horrible to her but them trying to teach bite work is a possibility because they also had a very dominant male who they did do it with but didn't do it right so he learned to bite people.It's possible, but it could also just have been someone who wore a large jacket scared her. Dogs, not just rescues, reacting like that to certain clothing and people is very common. My first Boston bit someone jumping while wearing a backpack. Luna currently barks like crazy if someone is carrying something large. But I know Luna can very easily become scared of little things (like USB cables touching her) so we can't assume someone did something absolutely horrible to her in the past.
