Awwww, but these precious animals are only mean if their owners are mean.
As a person who has worked in insurance and seen many dog bite claims, I would say 75% are from pit bulls. And given the damage they can do, I would say make them extinct.
Now let's see how many parents and grandparents will post about how sweet they are around their babies. Which is great, most are good with members of their own pack. It's the rest of us that have to pay for your stupidity.
I've worked dog bite claims too. Always interesting to find out the dog's name. I had three in a row named 'Rambo'.
