Exactly, by trying to create a "better" reputation for a breed you can also put people in danger and the dog honestly, cause they're the ones who deal with the consequences of crossing that line.
Labs are the "perfect" breed, great around kids, etc. etc. So why did two labs wander onto my property and then one almost full on attacked TWO people when they went to try and stop them attacking my chickens? If it had been an "aggressive" breed they would've approached with more caution or not at all, but they got complacent because it was "just labs".
Breed doesn't matter as much as individual dogs, breed still has a say but people make too many blanket statements in BOTH directions.
And yeah, only dogs I've ever actually been "bitten" by were chihuahua, Maltese X, and one of my terriers. But those bites don't quite compare to the Dane X bite my colleague received, to the face, that landed them in hospital.
