It's so big that he has a hard time carrying it around. He occasionally misjudges the width of himself + bone and smacks it into doorframes or kneecaps.
Elias likes to keep his bone as close as possible, so nobody steals it. He also likes to taunt family members that He Has A Bone And You Don't.
P.S. Elias thinks he's a 60-lb lapdog. Which is to say, his butt fits in your lap. Sort of.
* Yes, it's a rawhide bone. No, he doesn't get to eat it as rawhide makes him sick. He just likes to carry it around and show it off - it'll be months before he takes a nibble, and then we usually donate it to our neighbor who has a Labrador that love rawhide.
