Last week I responded to cover an officer on a call where a 15yr old girl was being attacked by a pit bull.
The dog had dragged the girl down the street, but when the primary officer and EMS arrived (before me) the dog was gone. As they treated her and loaded her into the ambulance, the dog returned.
I arrived to find a huge crowd of people in the yards and sidewalk, an ambulance crew trying to load the girl up in the middle of the chaos, and a scene right out of the movie Gladiator in the middle of the street. Here is what occurred prior to my arrival...
When the dog returned he had tried to attack a person getting out of his car. The large number of people in all directions made the use of a handgun very dangerous. The officer deployed his Asp baton while the firefighters armed themselves with whatever they could...one with a fire extinguisher, one with a pry bar, and one with a long "gaffing hook" used to pull down loose debris during a fire. They got the dog's attention away from the driver of the car, and quickly found themselves the target of his attack.
When I rounded the corner the street was filled with CO2 "smoke" as the extinguisher-armed firefighter tried to ward off the attacking dog. It was having little to no effect. As each person struck the dog, he turned his attention to the new attacker and went after him. The street filled with smoke, with men wielding a variety of weapons, a crazy dog in full attack mode, an ambulance crew scrambling to load their patient, and a crowd of screaming spectators, made for quite a scene when I pulled up!
I had an instant to choose between 2 weapons that I could add to the mix that was already there...a 12 gauge beanbag shotgun and an AR15 rifle. With the large number of people in all directions, I felt my best chance of getting the "safest" shot was with the beanbag gun.
As I ran up, the extinguisher went empty. The dog was trying to eat the nozzle. I found the clearest backdrop I could find, took the sharpest angle downward I could, and shot the dog in the ribs (immediately followed by screams of people who were horrified...believing I'd just killed the dog with a shotgun). The dog yelped, jumped back, and immediately went after the firefighter with the pry bar. I fired again as the dog jumped, missing low. I immediately fired again and struck the dog on the left shoulder. The dog spun away and began limping down the sidewalk.
I stayed in the street and followed alongside the dog looking for a cleaner shot...ready to switch to my handgun if I could get a good backdrop. The dog was clearly hurting and trying to get away, but after a short distance he just stopped and looked at me. It looked to me like I'd "broken" him, so I yelled "SIT!!"...and he obeyed the command. I followed up with "DOWN!!" and he slowly laid down. I yelled "STAY!!" followed with "GOOD BOY! goood boy!" and covered him with the bag gun until animal control arrived. He was captured easily and had a look on his face that was like "save me from the mean men!!".
Humor aside, it took a tremendous impact (point blank 330fps lead shot filled canvas bag...twice) to overcome the dog's desire to bite. When he was limping away he looked like he got the wind knocked out of him. A full blast from a fire extinguisher just made him more aggressive. Strikes from a pry bar and an Asp didn't phase him at all. I doubt OC would have made a difference once he was attacking, and it never got used because of how close everyone was and how dangerous a spray of OC could be to someone trying to defend himself from the dog. The primary officer said his last plan as I arrived was to try to get the dog to bite the Asp and try to shoot him in the head with as much downward angle as he could get...and he was very very worried about it.
Using a handgun would have been extremely dangerous. My missed beanbag round tore on impact with the street and peppered an occupied vehicle downrange with #8 birdshot (minimal damage). If it had been a handgun round it could have been *much* worse.
Since everyone made it ok, there was quite a bit of joking afterward about the "Gladiator" approach to fighting the dog.
I responded to a dog attack last summer where a pit bull had bitten the owner's nephew. A single bite, just above the ankle, broke the 12yr old's leg and the wound was gushing with blood. It was completely crushed.
