Can I bring my small dog if I have note from doctor saying I need him because I'm hard of hearing

That type of question should be brought to them. I do not know the answer.

If it is a service dog that is task trained to help mitigate a disability then yes. If it is an ESA or a pet then no. A doctor's note is not required

I don't think so but you can call first.

I'm sorry I wish I could help, but you can go on there website to see or give them a call
