She wants to turn her dog into a service dog?

So small little backstory.

I became disabled two years ago and recently I have talked to my psychiatrist about getting a service dog. He was on board for it if it helped me create a better quality life for myself. So last year I went out to Petland and adopted a sweet 12 week old dalmation. Right now we're on month #3 of training and is doing phenomenal! And working towards becoming a certified dog trainer.

One of my best friends cousins is also disabled and reached out to me personally about turning her dog into a service dog. But I'll be honest. I wasn't happy going over to her house and if I'm being completely honest I don't think he's a good fit for service. I think the most confusing part is she kept calling him ESA instead of service like it was this back and forth thing where she couldn't tell the difference between the two. Anywho, when I went over there her dog was barking a lot and doing a lot of growling at me. She gave me the heads up he's not fond of strangers so... problem number one. I had her take the dog outside on a leash to see how he does with leash pulling(if any pulling at all) and she barely has any control of him. So problem number two. And last but not least, she allows her dog to use the bathroom in her closet.... yes seriously. I guess she had trained him to use the closet as a bathroom with a litter box in there for him to go. She's a big woman and has ankle issues but she wants him to be more for emotional support but she wants to be able to take him out in public...🤨🤔

I'll be honest from his behavior and what little training he has I wasn't too sure what to tell her. I did tell her I wasn't sure about him being specifically a service dog due to temperament and other reasons. She didn't clarify anything about if he's potty trained outside but I guess every once in awhile she does let him out(hence the litter box). With being stuck on not sure what to do to help her I did let her know he needs basic training and left her with my service dog information book for a week to help her. But to my understanding she discarded the book and hasn't looked at it according to my bestie(they live together). I would like to try to help her but she wasn't very clear about what she needed up front and it's concerning. It really just sounds like she wants to be able to have access into the store with her dog to me. I can understand needing a service dog for mobility since she has a bad ankle and I know she has other issues too but personally I just feel uncomfortable telling her he's unfit for service. When talking to her too it really sounded like she wanted me to do it all on my own which I understand, she even offered to pay but I'm not trying to work her up to basic training only to then find out he's still not suitable for being a service dog.

Any ideas on how to handle this? What's your thoughts?
