Yes they can make sure you legally have a service dog. Otherwise you are imposing a huge inconvenience on everyone by bringing an animal into a bar or night club. Use your brain. Why are you trying to go to a place like that with your animal? There's plenty of trouble makers with no legal right to a service animal, who just go places they don't belong, just to start trouble. Any business has the right to not allow animals, refuse service to anyone for any reason, or make sure you're legit and not just some trouble maker looking for confrontations.
I'm so happy to see that they don't allow random animals in the club.
