This is my personal list of must have items for training any dog. I am not an expert.

However, I am not sure what the qualifications are. Maybe if someone could explain them as it applies to dog training, I might be able to tell. Enough on that, here is my list of must haves.
1. A crate large enough for the dog to turn around in comfortably.
2. Some type of chain correction collar.
3. A leash about 6 feet long. I prefer leather, easier on the hands.
4. A long lead about 15 feet long.
5. A higher pitch happy voice.
6. A lower pitch firm voice.
7. A constant set of words for each action you expect from your dog
In my home a new dog will be in his crate, or on the leash, until we get some of the basics down, like sit, stay/wait, let’s go, down. When it’s time to go outside it is on leash, and before going out the door he must sit, wait, and then let’s go when I’m ready. Letting your new dog run the backyard puts him in control, not you. To have control you need a leash or long line to enforce the commands you are giving.
Obviously, this will not fix her dog issues, and I agree she needs some real help. Unfortunately, I’m not sure what to suggest.
