I probably answered the first time you posted as MidwestMom. I probably told you my story.
I would call the police. But my priority after that would be to get her help in a live in mental health care facility unless you give up your dogs...all of them. She is still doing this after all this time.
My guess is that she will be diagnosed eventually with attachment disorder, which is pretty much the same as antisocial or Conduct disorder.
I am really sorry. This is sadly common when children are neglected or abused early on. It's hard to treat and can turn dangerous. Often seen when a child lived in an orphanage or foster care and had no primary loving caregiver and I am sure you have done your best. Unfortunately, love doesn't cure it.
Sorry again. See what kind of out of home mental health care you can find for trauma. Early neglect is a trauma to the person and you don't grow out of it. Does she play with fire?
Hugs to you.
