i think they have them in use already, i remember seeing them on the military channel, one of the future weapons show, they used them for crowd control in afgan.
No, I haven't. When I look out my kitchen window, he is usually laying under the pecan tree alongside my driveway, but now when I open the door he runs - getting knocked on his can 4 times seems to have taught him a lesson.
In color/markings/conformation he looks like a rottweiler - only about 4 inches tall at the top of his ears. He can run under my Corolla, head up, and not hit anything. I did find out that the neighbor behind me moved out last week, and he had several dogs - this might be one he abandoned. The neighbor that was swatting him with her broom says he is eating the cat food she puts on her back steps for her tomcat.
