Exhausted, the dog gives up and starts sinking in the water as the air leaves his lungs. The whole time, a group of men in lab coats watch and commentate in their nonplussed British voices.
Finally, his motionless body settles at the bottom of the room, before being dragged away by a hook that grabs him by the collar.
But this is nothing compared to what's in store for you if, for some reason, you decide to keep watching this movie. The most soul-deadening scene by far starts when one of the canine protagonists is spotted by a hunter with a shotgun.
The hunter starts calling the doggy, and then he ... puts the gun down. He actually just wanted to pet him! Not everything in life is death and cruelty: There are also kind, friendly people out there. And then the dog excitedly leaps into the man's arms and ...
... accidentally shoots him in the face.
How do we know the shotgun wasn't pointed at, say, his dick or something (which is at least survivable)? Because they goddamned show us, that's why.
"It's just a really bad nosebleed. From the eyes."
That thing about the man being friendly with the dog? That was just there to lull you into a false sense of security before dragging you back into the cold, terrifying world of British children's animation. The dog sees the man's lifeless corpse and runs away, now a murderer.
Those aren't spots. They're bits of brain.
The worst part? This doesn't have anything to do with the plot. The man is never mentioned again, so presumably they just put the scene there to freak us out (it worked). Oh, and later on we see a re-creation of the scene from First Blood (released a couple of months earlier) where a guy falls from a helicopter and dies -- except this one's even more gruesome, because at least Rambo didn't go back and feed on the man's corpse.
