I've nearly been attacked several times and have been attacked when I was younger and weaker. I carry a weapon when I jog and I've had to threaten to use it even recently. Just the other day, a rotweiller charged me. Then a few days later, it was a chow. THe owners let their dogs run loose out here in the country. I won't hesistate to kill them if necessary. If they bite me, I'm a revengeful motherfucker and there will be hell to pay.
