It is told that 2 men got hung upside down and got their throats slit, but it's never shown.

The severed arm of the alien is found outside under a dead sled dog. It's taken inside to be examined.

Some sled dogs are attacked and killed by the alien. It happens outside during a snowstorm at night so it isn't very visible.
