In response to Tanya , yes I have observed my Kodiak doing this.  I call it
the "Loot-n-Scoot" maneuver.  He steals a toy from Musky and then proceeds
to scoot all around the room backwards with stolen toy in hands pulling the
toy under himself as he moves along!!
 
Good things to all,
Babar and my fuzzy family......Musky, Kodiak, and Jpeg
