Public transportation is in europe very common, but normally there are rules that you are forced to leash your dog AND have that typical mouth-barriers, when taking it with you on public transportation. By doing so, there hardly can be any incidents.
A small dog might get away with riding a bus but not a fifty pound Mastiff or similar-type pet. They would be turned away by the driver unless trained as a service animal and people do try to sneak their pet on that way from time to time.
