poor baby. that one leg has problems in the pastern joint itself, looks like she has the ocd
disease they get in their knees, beside being severely back at the knee.
At least you got her from the killer . I know you want to save her, but she will probably just be an expensive pet all her life. Good luck finding someone to adopt her and not try to use her.
This is why I am against heavy line breeding , besides the obvious physical , there could be internal deformities and mental issues .
You should also consider euthanasia as an option , as sad as it is, but it would be better than a life of pain if someone got her and tried to use her .
