I'm not sure this has been mentioned before. But it's quite a simple idea, really.

What about farm animals?

Chickens, the typical barn cat, mice, cows, sheep, horses, ducks, geese, swans, dogs (forgot the type), um...yeah. etc.

Would it work?

( you mean sheep dog/cattle dog)
Some of those would probably be hard to draw but to be honest its up to the artists! I think its a preeety good idea though!

I have a winyu duck/goose and i think it be easy to draw a chicken. But i have always loved drawing horses. Loved them since birth! literally. But i love the idea! Surprised it hasn't been mentioned before!!

:) thanks!
