We had an elderly woman and her small dog torn to shreds and killed in an upscale neighborhood in broad daylight by two loose pitbulls last year. The owner of those dogs is going to prison. Police had to shoot the dogs to get them off of the woman. I will shoot any large dog that charges me and doesn't obey my commands to stand down, period. We have a huge coyote problem in Oklahoma as well. Same goes for them.
