I think the stories related in the link show that a lot of the behavior is related to socialization. The dogs referred to in Thailand had very unkind experiences with humans whereas the dogs in Mexico did not. Here in the US, some people fail to give the dogs very many experiences at all, hence where walking comes in.
There's also the factor of dogs barking etc behind a fence because they feel they own that particular piece of turf. When they are one of many dogs hanging out on the street, they don't own it and act with what is considered by humans to be better behavior. So maybe it's a good idea to frequently bring other dogs into the home, so the dogs know that it's your turf, not theirs. I've seen a lot of normally nice dogs get extremely territorial when they are in vehicles.
