Slog

Abilities and Traits:

Slogs are dog-like creatures that appear to have no eyes and no front feet.  However, they know when there's an intruder in front of them, and they can even lunge up if their intended target is above them, so caution needs to be taken when jumping over them.

When a Slig is possessed, Slogs will obey it's commands, and even kill other unpossessed NPCs, mainly Sligs, on command.  It is possible to possess Slogs in Oddworld: Munch's Oddysee.

In Oddworld: Stranger's Wrath, there are Slegs that behave very much like Slogs, and they are used by the Outlaws and Wolvarks.  There is a giant  version of them, known by a Clakker as a "Giant Purple-assed Sleg".

Appearances and Mentions:

The standard Slogs first appear in the Stockyards in Oddworld: Abe's Oddysee, while escaping from Rupture Farms.

There are other different sizes of Slogs besides the standard sized ones.  The small ones, also called Sloggies, first appear in Oddworld: Abe's Exoddus.  Bigger Slogs appear in Oddworld: Munch's Oddysee.

In Oddworld: Stranger's Wrath, after rescuing Eugene Ius from the Outlaws and getting knocked down accidently into the hole by him, make Stranger say something by pressing X right before getting to the end of the hall.  He mentions Slogs when commenting on what the place smells like.
