Walking my puppy on Sunday, and a man with a huge GS stops me by garbling/shouting something unintelligible, so I sort of smiled and nodded then both dogs started playing. Suddenly his huge dog went for mine, (much smaller), so I dragged him away. As I walked away he was praising his dog. 
Today I heard someone shouting "Boy or girl?!" looked around me and surprise surprise it was the same man from the other day. I ignored him, eventually replying, "boy", (I presume he was demanding to know the sex of my dog) to get him to STFU. Then he shouted, "Are you smoking that wacky baccy" at me. (I was smoking a cigarette)
WTF could have been his problem? I'm a first time dog owner, so have been wracking my brains as to whether i committed some kind of dog walking sin.
