Yes as long as your pet is a service animal nobody has the legal right to question your pet to see if it's a service animal but if they ask all you have to say is that it is a service animal they do not even have a right to ask you for papers or identification to prove it unless you're traveling through airports or bus other than that you have the legal right to have your pet in the mall with you
I really don't now
I went there with our service animal and no one bothered us but our lovely Princess was wearing her vest. We have been stopped at other places whenever she is not wearing it due to the heat.
