Control your dogs. There is no argument in this really if a dog attacks or appears to attack for no reason you have a right to protect yourself. The LEO's were only coming by to make sure everything was ok. Actually kind of nice of them, but then after killing the dog I could just hear them say "Lets get the hell out of here".
I have been attacked by dogs on three occasions and the dogs in all three tried to bite me, one going for my wrist and the other my throat. Two of the attacks were turned by me kicking the dog as hard as I could.
The one attack that went for my throat, I have no idea what happened, I was about 10 years old and jumped this fence playing hide and seek, someone new to the neighborhood had moved in there and they had a German Shepard that I did not know about. It jumped right at me for my throat. Next thing I remembered I was on the other side of the fence looking at him barking and spitting. I had a tear in my shirt right next to my neck but not even a scratch. I have no idea how I got away or over the fence, its like someone reached down and pulled me out of there. All I remember was looking at that mouth with all those teeth and it was only a foot away from ripping my throat out, then poof, I was safe.
