Pit bulls are such a plague

A few weeks ago I was passing out flyers around my neighborhood for a community event and I noticed my neighbors car in the drive way with the door open. I shouted hello to him but he wasn't in his car, he was in the house. His 2 mix breed pitbulls jumped out of the car and ran over to me by the sidewalk and started biting my shirt and pulling me. I didn't scream or run I just put my hands in the air and talked calmly and backed away but they wouldn't let go. A nice lady pulled over in her truck to try to help me and my neighbor finally came out and called them off. They didn't hurt me but they totally ripped up my sweatshirt. I hate pitbulls. I talked to him at a neighborhood meeting and he apologized again and said they have electric collers but that the batteries are dead. He literally has no yard and they just hang out by the sidewalk where kids walk to school everyday. He said he used to have beware of dog signs up but the trees were cut down. I carry mace now.
