Dog’s Severed Head Kept Alive Via Machine

I found this a little disturbing, but still not sure if it’s real or not. Supposedly this is a video of Russian scientists keeping a dog’s severed head alive using what they call an “auto-injector” which is basically a heart and lung machine. What do you guys think? The dog reacts to the scientists poking and proding it, but the video is so grainy and “old looking” it could easily be fake. But real or not, the video is a little creepy, poor puppy.
