First off, that is one ADORABLE free-wheelin' 
hound you have there, heeheee! I've always loved 
pekes for their faces, so expressive. :)

And second, whether it's in your field or not, 
congrats on the new job!! I did temp work in a 
file room for three years after college, until I 
finally managed to wriggle into my chosen career 
path. The important thing is not starving while 
you wait for an opportunity to appear. *grin*

Well, in honor of your happy news, I hereby 
present one sketch which covers two of your 
categories. Hatori is both a doctor AND an 
animal (at least, if you hug him). I doubt he'd 
ever be anyone's pet, though...

Congrats again! :)
