One concern raised about dogs on public transport is that dogs won't behave themselves. However, if they are well-socialised and disciplined, then there is every likelihood that they will be much more respectful, well-mannered and better behaved than many humans who catch public transport.

My border collie sits, drops, shakes hands, doesn't jump up. In fact, everyone loves him for not only his handsomeness, but because of his mild nature and beautiful manners. He would be very well behaved if allowed to travel on public transport with me.
