Need some help with my dog.

Thanks! I'm not saying her abuse causes her to be like this, if someone raises their voice however, or sets something down hard she hides and starts shaking, or if you go to pet her too fast, she thinks you're going to hit her.

many people take actions like this as a sign of abuse. it CAN be but just as often it's not. Weak nerves and poor temperament are just as likely. Honestly, they are more likely.

Get a behaviorist to come in and help you with training.
Until then, manage her environment. If you are worried about her charging the door, set up baby gates so that she can't get near the door. You can get "shapeable" gates and fence off the area around the door.

Microchip clinics are super common. Check with your local shelter. Many areas, especially cities, have clinics where they microchip for FREE. All you pay is the registration cost.

Harnesses are a bad choice for dogs that tend to slip their leash. They are easy to slip out of and encourage pulling

No behavior suggestions here but there are gps collars for dogs. My mom had one for her dog for a while. It would send texts when the dog was outside the home base. I think it was kind of pricey and if I remember right it also cost a yearly fee. She got it because her other dog got out and went missing while I was watching it and we never found him. She stopped using it because the texts got annoying and that dog was never one to run off anyway. We did discover that it could track the dog while we were hiking in the mountains so they should work out in the country too.
