Hello and thank you for asking your question. My name isXXXXX will try to help.
Dogs can get very traumatized from an attack. If she were mine, I would put her on an anti-anxiety medication for a few months. Also, try to take her around your friends dogs or dogs you know will not bite her. You could even take her to an obedience class where the dogs behavior will be controlled. Try to get her out, on walks or in the car, as much as possible. She needs to build, and regain, confidence again. I think you will be able to get her out of it. It may take a few months. I hope this helps. If you have additional questions, please reply. Thanks
