Here is what someone that went after him said:
This guy was NOT exaggerating! I have worked with dogs ALL my life and have NEVER seen anything like this before. The dog is in a huge fenced backyard and he has claimed it as his own. When he saw me on the deck, which is about 8 feet up, he tried to climb the lattice to get to me. He was growling and snarling and I could tell he meant business! He was biting the rails on the deck and trying squeeze through them even though they were only 8" apart. I tried to wear him down by running along the OUTSIDE of the fence but I was exhausted and he was only getting angrier. We tried a pole noose and he snatched it out of our hands, got it from around his neck and chewed the metal pole into several pieces! I told the homeowner that he is probably going to have to drug this dog to get him somewhere. I just feel sorry for the person in the room with him when he comes to! He must weigh 200 pounds and is solid muscle. Good luck to ANYONE brave enough to try and tame him.
