But the choices aren't just "OMG HAI" or "bites strangers who touch me" - there are all sorts of happy mediums where it's possible to have a dog who is timid or suspicious without biting, much like Adrianne's point that aloof doesn't mean fear or overt aggression. Having lived with both kinds of dogs - I find aloof and timid/suspicious quite a bit easier when out in public than OMG HAI. Pip is perfect for me for the dog park because neither one of us really wants to socialize with others, we just want to go for our dang hike, yet he responds to pushy, affectionate strangers with extreme tolerance. And although honestly I enjoy the OMG HAI dogs, too, at a certain point (coughMaisycough) it gets taken it to such an extreme degree that it can annoy the every-loving %$^! out of me.
