If you're getting a ride from a friend, co-worker, family member, etc., does the driver have the right to refuse your dog?
Absolutely not. My dog is my guide and nobody has the right to tell me what I can and can't do.
It depends on whether I'm asked politely or told to leave the dog at home.
It depends on the event for me.
I'm riding with someone else. If they have a reason for not wanting my dog I'll respect that.
Other, please comment.
