I want to go through the proper channels to get a doctor's note for a pet. I've been putting off getting an ESA for too long, and it's finally time, but I want to make sure I do it the right way. Can I go through my regular doctor who already knows my history, or is there a specialist I need to see? Are there any extra charges I need to prepare for? What extra paperwork might I need for my managers? Thank you in advance!
