man, this is a crazy story. I mean crazy! But i don't know what is more amazing...the fact that your dog had no hesitation running into someone's house, or that someone would be so crazy to empty a magazine of bullets inside his own house, or that this person is such a bad aim that he emptied a magazine of bullets without hitting the target even once?
I mean, really, this has got to be one of the most amazing stories i've read in a long time. Do you have any idea how much bullets ricochet? Not to mention the plaster, cement, and any tiles on the floor would be flying everywhere. Houses here are made of concrete...there would be some serious cement splatter, not mention the dog would be bleeding everywhere.
Plus, there's the cost effectiveness of emptying a magazine of bullets. Bullets are expensive here. I'm not sure it would justify the cost of using all your bullets on one dog...unless the dog is eatable. Was gunman Asian?
Another thing, we haven't into the logistics of the bullets penetrating the walls and hitting other people in the house or the neighbors house. Bullets have a tendency to carry through concrete block, but of course, this depends on the caliber of bullet. Was he holding a .50, 30-30, or any kind of Buffalo looking rifle or machine gun--which would have been secured to gun turret a large tripod-looking gun mount in his living room?
Another thing to consider--i've been around a lot of guns, the noise within the confines of his room would have left a ringing noise in his ears, your dogs ears, and your ears if you were in the same room. did you notice him wearing any ind of ear protection...maybe a pair of winter earmuffs?
Some redneck gun fanatics will have a gun turret securely mounted to their kitchen table, Dining room table, or bolted down into the base of the concrete floor, or on top of a dresser in their living room. Did you notice any of these things while you were in his house?
PS. In the event that he hit your dog with a large caliber bullet...did you notice any recognizable pieces of your dog on his kitchen cabinets or living room walls?
