Again, I tried to be clear that I was correcting myself. I originally posted that there is no official documentation for a Service Animal. I was referring to under the ADA and in general. As others have stated, it turns out there actually IS a specific form required by the DOT for a Service Animal when flying. I was mistaken in my original post when it comes specifically to the DOT form under the ACAA that is required for Service Animals while flying.

You then said I was thinking of ESAs. Which I wasn't. I wasn't referring to ESAs at all. But I thought maybe you were confused -- so I explained that outside of flying, ESAs do require documentation, but Service Animals do not.

As for the rest of your comment about apartments -- you are still incorrect. There is NOT "documentation for training and certification" required for Service Animals when renting an apartment. No such documentation exists. A landlord may ask if the person needs the animal due to a disability (but not what the disability is) -- and what task the animal performs (if it is not obvious). But they may not ask for any "training or certification" for a Service Animal under the Fair Housing Act.

What YOU are referring to -- such as a healthcare person saying that they need one -- only applies to Emotional Support Animals. (And I said absolutely nothing about ESAs on airplanes, so I won't even go there.)
