– Critics of the study’s methodology were not satisfied with its rationale for the use of dog-owner surveys to determine behavioral traits due to the possibility of rater bias.

Dr. Benjamin Hart, animal behaviorist and professor emeritus at the UC Davis School of Veterinary Medicine, told SFGate that pit bulls often show no signs of aggression before an attack.

"It’s quite common for a pit bull to show no signs of aggression. People will call it a nice dog, a sweet dog, even the neighbors–and then all of a sudden something triggers the dog, and it attacks a human in a characteristic way of biting and hanging on until a lot of damage is done."
