I wouldn't say that a DA dog is not socially confident. My APBTs were not DA because they were not confident around other dogs, rather they just thoroughly enjoyed the idea of a good fight.
Say what you will, but there are dogs that have no problems fighting other dogs on their own accord. No one is saying you should let them, but people do need to acknowledge that there is nothing wrong with (off) about a dog that wouldn't mind a scrap now and then. Dogs will be dogs.
I love that my dogs are not overreactive dogs. Sure, I work on teaching my kids (and everyone else's kids) how to properly interact with them, but I love knowing, that should one of my boys run up to the dog suddenly or accidentally step on the tail or trip and fall by or on the dog, my dogs would not overreact in a negative manner. They are calm (ok, happy tails don't count) when in groups of people, and I have no qualms about going out for walks or anything else. However, we all know that certain breeds are for certain people.
Boxers are just nuts. Happy nuts most of the time, but still nuts in hyper-drive. lol (However, I am seeing a quick rise in very unstable/ill-temperamented boxers. Kind of strange.)
I will admit that I like Standard Poodles. There's just something about them. I do no, however, care for the "widdle ones". Unfortunately, I've not had the best interactions with the smaller poodle varieties (as a vet tech). They ranked right up there with the Chihuahuas and Poms in terms of their willingness to detatch a finger from your hand.
