A week ago Saturday morning I was working on my truck and had my male Lab in the front yard with me, no leash and no collar(mistake #1). I was under the truck when I saw my Lab go by, so I rolled out and jumped up to see him headed up the street towards a large Pit Bull. I yelled at him to stop, which he did, and then I told him to sit which he did. I got to my dog before the Pit did, but as soon as I grabbed my dog by the neck to get him out of there the pit attacked us. Not wanting to let my dog be defensless or to get bit, I let go and the ensuing fight was as bad a dog fight as I had ever seen. Fortunately, my 100 lb Lab more than held his own with the Pit, he grabbed the Pit by the head and neck and wasn't about to let go. The Pit finally got loose and inflected the worst bite of the fight, which took out two small lower front teeth of my Lab. Finally a neighbor showed up with a baseball bat and was able to hit the Pit in the head, which ended the fight long enough for me to get my Lab away from the Pit. Even though the Pit was never able to get my Lab by his neck, I am sure it would have only been a matter of time till he did, a Pit won't quit. As it turned out, the Pit was a stray, he had a collar, but no tags. Animal Control picked up the Pit and he was put in quarantine, they wanted to pick-up my dog, but we were able to talk them into home quarantine for him. Since rabies is rampant in our county at the present time, and I got scratched, I had to go the the Dr. $100, the Vet bill for my Lab was $150 to look at the bites on his chest, fortunately none to his face or neck or ears. I know there are responsible pet owners out there, and there are Pit Bulls that are good pets, but these dogs were bred to fight and it is just instinctive to them. This dog will meet his maker in the morning because he had an irresponsible owner who wouldn't take care of him.
