Had a 55 lb female pit bull take one out. Didn't have a scratch on her I couldn't believe it. She also caught 17 birds (that's just the ones I saw). That was one fast and strong bitch. Man I miss that dog.
its always the female dogs that are the killers. i used to have a female pit that was 45-50 pounds tops and she would kill all kinds of shite. coons, possums, birds, snakes, anything. she would leave the carcases on the back porch and come in the house smelling like a shithouse rat. my 85 pound male pit doesnt kill anything, ever; 0 kills in 4 years.
