Howie and Larry: They don't know they're tiny.

Everyone who first meets Howie (named after Howard Stern) and Larry (for Larry David) thinks they are brothers.  Who can blame them?  While Larry is a bit bigger than Howie, they both have the same wiry hair and coloring.  But the friends were adopted by their people from two different rescue organizations and nearly a year apart.  Despite their small size, Howie and Larry have big personalities.  Larry is an accomplished explorer of the backyard, and Howie displays his over-confidence by picking fights with the three huge dogs on the other side of the fence.
