rehome my herding Shepard mix dog Mango. Mango is 3 years old and we rescued her from the shelter when she was 1.5 years old. She has a bite history, nothing serious enough to need medical attention. However my fear is that it will escalate to that with her not being in the proper environment she needs to live comfortably. She has never been dog aggressive but has recently started to attack our little dog and punctured his leg. I live in a converted cargo van and just the risk of her possibly hurting a stranger since we are going to be constantly switching her living environment. We can't give her the stable living situation she needs to live her best life. I have spent thousands on getting her trained in hopes it would help her nervousness, anxiety and aggression. It has helped somewhat but I believe she needs a yard and a home with bigger dogs. She doesn't bite all the time but every 4-6 months she likes to go for an ankle. She is so smart and we love her dearly but don't think we are the right fit for her anymore.
