Collar for Sumo the Mastiff

Sumo's a pretty big mastiff.  His 28" neck means my wife could wear his collar as a belt.  I laminated the collar so the arms of the studs wouldn't catch is Sumo's hair.  Might take a couple weeks for the leather to adjust to its new shape but I'll wager this'll be the comfiest collar Mr. Sumo's ever had.
