Caucasian Ovtcharka (Caucasian Sheepdog) (Caucasian Shepherd) (Kavkaskaia Ovtcharka) (Caucasian Owcharka) (Caucasian mountain dog) (Sage Ghafghazi) (Kavkazskaïa Ovtcharka) Its on the website, you pulled the pic from.
Judging by the padding they are wearing it's probably a training exercise of some kind to teach the dog to go after anybody with a gun. Of course, it looks like that dog goes after anybody regardless of if they have a gun or not.
Looks like the type of dog that would pick up a gun, hold you at gunpoint, take your money, beat you senseless, then drive off in your car.
