As one who ended up in the ER from a neighbor's male pit bull, I agree. I was in my own yard beside the fence between yards when the dog came up and part way over the fence and got my hand such that the entire weight of the fifty pound dog was held by my middle, ring and little fingers. I had to rip my hand out of his mouth as if it was a shark attack. 911 was called for me and animal control came for the dog.
After ten days the dog was put back in the yard because I was the only reported injury (there was at least one other attack that I know of). It took months for my hand to heal, infection, loss of motion, some nerve damage, scarring. To this day if I'm near the fence he attacks. BTW, at the time I had two dogs of my own that were friendly to people and neighborhood children.
Be prepared to be attacked now by the PBT apologists here, who are legion. Blame the victim, and the owner, and the breeder (not for deliberately breeding these characteristics, because according to them, it has ZERO to do with genetics, but for raising them wrong for 3 months).
So sorry you went thru such.
Do you carry when in your back yard?
