It is the law that they have to let in a service dog. A service animal is any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, Emotional support dogs are not considered a service dog. The dog would need to be identifiable, usually with a vest.
Cattle dogs are usually left to guard the truck. Identified service animals are allowed in.
I don't think so. I have not seen any signs/postings saying that's ok.
