I absolutely despise pitbulls and believe every one of them should be euthanized.
A couple of years ago I went to my employee's 2-year-old son's funeral after the families long time babysitter's three pit bulls ripped him in half.
Apparently the three pitbulls got into a fight outside in the backyard with each other and the homeowner/babysitter went outside to break up the fight.
When she went outside she left the arcadia door open and the 2-year-old followed out behind.
The family pitbulls turned on the homeowner ripping a huge hole in her head and arm.
Then they turned on the 2-year-old boy and immediately ripped him in half in front of his 4 other siblings who were watching from inside.
It has nothing to do with how they are raised It has to do with their breed. Every dog is capable of attacking or biting someone but they let go/stop afterwards, pitbulls don't. That's the difference.
