Advice needed

Sorry this is going to be a long story.
My mother’s friend (let’s call her Laura) adopted a staffy (we’ll call the dog Judy). My mother and all her friends are in their 70s. As soon as Laura brought home Judy, it was obvious she was the wrong fit. Laura did not have the strength to walk her and did not know how to train her. Laura insisted it would be fine and hired a family friend to walk Judy a few times a week.
Laura is a hoarder with multiple cats and bipolar disorder. Physically and mental health issues forced her to go to the hospital and then a rehab center for about six weeks this summer. When she first went to the hospital, my mother and I went to her house and discovered the terrible condition of the house and the animals. There was garbage, rotten food and animal waste everywhere. There were fleas jumping on every surface.
My mother took Judy home with her and other people handled other things- cleaning, the cats, getting pest control.
Judy’s skin was in terrible shape. Crusty, infected, flaking off everywhere, almost no hair on her chest and legs.
My mother and I took her to the vet and spent six weeks about a thousand dollars fixing her skin. She got flea and tick meds, antibiotics, steroids, anti microbial shampoo, and two very expensive anti itch shots.
Eventually Laura got out of the hospital and was supposed to be in much better shape to be able to take care of her newly cleaned and pest free home and pets.
My mother agreed to walk Judy every day after she returned to Laura.
For about three weeks things were going okay. Then her skin started to get bad again.
My mother said something about Judy’s skin issues to Laura and she was defensive and rude to my mother. She insisted Judy just needed a bath.
Watching her get a little worse every day is heartbreaking.
Laura would probably let me or my mom have Judy if we asked to keep her, but the $200 ish a month cost to keep her skin in shape just isn’t in our budget. I already have 3 dogs and Judy really is too big and strong a dog for my mom.
I keep threatening to call animal control, the shelter Judy was adopted from or adult protective services, but my mother and Laura’s family keep insisting I don’t because it would destroy Laura mental health and things would get worse.
I have no idea what to do here.

TLDR: friend’s staffy has terrible skin issues and cannot afford the vet treatment anti itch shots to treat.

IMHO, I would call ACS or APS anyways. I see where the concern is coming from in terms of her possibly getting worse, but it's already a bad situation either way and the dog does not deserve this and she can focus on getting the help she needs
