I support you but understand that if others in the complex can't visibly see that you have a disability then they will want to know why you get to have a dog and they don't. It is only natural. You might say in a friendly response that your dog is needed to assist you with things that others don't need help with. More than that you can say is personal but letting your neighbors know that you need the dog for help should stop of the questions.

Sad you had to resort to litigation but it had to be done. Let us know how it goes.
