I am also deathly afraid of dogs and It was always my turn to go to the door when there was a crazy barking dog.
LOL. I have a friend up the road from me who has a farm with 3 American Bulldogs running loose at all times. Says he has never ever had a visit from the JWs.
I didnt like Field Service one bit. I liked talking to people about religion and still do but I hated my props, ie the books and magazines. I felt like the presentation didn't do the concept justice; and knocking on doors? Well how to annoy people!
Trouble is I think most JWs do it for the wrong reason. They don't want to "save" all these poor souls living in the time of judgement, they just want to get brownie points so they themselves will be saved.
