[Shelby&Seymour]

I think that Seymour has a very petite "non-boyish" face. He is sometimes mistaken for a girl. Shelby has a rounder teddy bear face and she is a little bigger than he is, which also will sometimes let people think he is a girl, too.
But....... he definitely is a boy........ he is always the first to bark to warn us (& his big sissy) that he thinks we need to take notice of something.
