For myself I look at what the breed was designed for and then take into consideration the motor patterns and the enhanced drives of each breed. Were some of the motor patterns deleted, which ones were enhanced. To add to this some of the most dangerous dogs which have been involved in mauling deaths have been sweet dogs and kissy face when their predatory drive has not been tapped. When you have a breed like an APBT, Stafforshire Terrier (most terriers), Rottweilers etc which were breed to have the full series of motor patterns with enhanced drives then learn about the drives and make sure you are a responsible safe owner. To yell at some one and tell them that all these breeds are sweet kissy face dogs is covering up and just masking the problem...it is not solving anything.
When I rescued my Rottweiler I understood the breed, I took into consideration they were breed to chase cattle and grab at their hocks. Do I think my Rottweiler is safer than a Golden?? heck no, that is just plan silly. A Golden Retriever has been bred to grab bite but not to kill bite. A retriever, sheep herding dog and pointer, livestock guardian dogs, sight hounds are mucg safer than a cattle drover or a terrier bred to kill rodents.
It's quite logical when you sit down and think it though. Too many people are trying to put on that thier breed of choice would never hurt any one and it's only a bad evil owner who creates a bad dog...wrong. It takes a naive person, even a person who will spoil one of these dogs to create a dangerous dog. I have met some sweet APBT's that are loving and sweet that have gone into predatory drift just as quick as I could blink my eye. One moment playing with you, then a head hung low and attacking due to predatory drift...aggression? not exactly, its just a drive or motor pattern the breed was bred to have and it is enhanced.
Education is what we need.
