I suppose that is a possibility but I don't think it is likely. In my work as an electrician I have worked in many places over the years and I have had pretty good luck making friends with family pets. I've even had a cat give me two mice as a thank you gift after I gave it tuna fish from my lunch. I've made friends with a lot of dogs in that time but I do have to admit to being prejudiced against pit bulls. The breed was bread as a fighting dog and is naturally very aggressive. Every encounter I've had with the breed has been a negative experience.
I was working on one job site and had a pit bull break through a fence to try and get at me. It was the dog's bad luck that I was doing conduit work and had the tubing bender to hand. A strong swing that was powered by fear only stunned the brute. I'm a six foot four inch (193 CM) tall, two hundred and thirty five pound (107 Kg), construction electrician. That bender connected with the side of the dog's head and threw him a good four feet but he was back up trying to get at me in seconds. While the dog was trying to get at me another electrician jammed a powder operated tool against his body with the trigger pressed. It was only the threaded stud that went into his back that caused him enough pain that he retreated.
The animal control officer that responded said it was more likely the startle effect of the discharge of the powder operated tool, in this case a Ramset, that caused the dog to run away. He had ten years on the job and had pit bulls with broken legs still trying to attack. He claimed they were relatively insensitive to pain once their blood was up.
I went to the commissioner's office and swore out a complaint for a dangerous dog. The dog's owner tried to get a stay on the destruction order but when I brought the bender to the hearing the judge heard my story and upheld the destruction order. The judge also ordered compensation for my lost wages but I never attempted to collect it. Since he loved the dog enough to hire a lawyer to try and save it I figured the loss of the animal was bad enough. Why poor salt on the owner's wounds.
