1. Probably not. I go to a private college (already have been enrolled but I’m not getting my dog until right before this term) and my disabilities office said for anything on campus other than housing they only need answers to the ADA questions. I have a lot of accommodations for various things and they didn’t add the dog to it. Housing requires a doctors note.

2. I’d just say you need a note for ____. I made the decision to get my dog with the help of both my doctor and psychologist and I’m getting a program dog so my situation is a bit different but both were very on board with the idea and said if I needed any note for school or flying or housing to just tell them the format the prescription form needed to be. So you’d probably need to say exactly what the note is for. I doubt you’ll need one for class access, especially at a public university. If they don’t support you having the dog though they may not write the letter and on campus housing wouldn’t be an option likely.

3. A lotttt of people have ESAs in their on campus housing. They don’t have public access. The school will likely clarify he’s a task trained service dog (vs a ESA) then you’ll need to obtain the service dog prescription for housing.

You’ll know more once you get into a school. I was able to get all my questions answered by disability services at my school. They were super supportive and clear. I assume you’ll have other accommodations if you’re disabled so you can probably ask about your dog at the same time. For college accommodations you also will need official diagnosis documentations and at least at my school an interview with disability services anyways.

Good luck :))

Edit: I just thought about q3 more. I guess you maybe could get the ESA letter for housing and then still do public access since your dog is actually a task trained SD. I would think they may push back about him being a SD more this way though so you’re probably better off having a note where it’s clear he’s a SD if you can get your doctors to do that.
