I do th get off and put the bike between the dog and myself thing if it seems insistant on agressiveness,but also usually have my .45 aimed right through his barking mouth just in case he IS that aggressive-I'm permitted to conceal carry though,I'd check my local laws first if I were you. I figure if they were to attack,I'll defend myself first,play the disabled veteran (which I am) card if needed in court later
