Interesting. I would never dream of not wanting my dog to bark at the door? Maybe it's just me(and I guess my girlfriend?) but I find it quite useful. The way I believe and have been told to deal with stranger anxiety is to tell people not to acknowledge at all and have a seat and engage in convo without paying attention to the dog till I brings a toy or nudges for pets. Works great for the people that listen, problem is not everyone does. People harder to train than dogs.
