I had a neighbor who got 2 pit bulls. They would attack anyone going down the street in my rural area. One day my son yelled at me that he couldn’t ride his bike home. I saw the 2 dogs, grabbed a piece of firewood and walked towards my son. they attacked me, went straight for my leg. I hit the first one real hard on the back before it bit me. They all backed off. I think I killed the dog, ran skreeching back to its house. Never saw it again. I know some of them though can be nice dogs if razed properly, but they are bred for fighting. They are kamikaze like attack dogs.
