I actually already own a pair as my cousin brought us back a small red set from China. I totally love them and currently use them as bookends. But I think they need some companionship in the form of two big turquoise doggy siblings.
The interior designers at Cullman & Kravis share the same line of thinking as me - you can never have too many foo dogs...

A few more great examples...
Pottery Barn (although this is a picture from their catalogue, they don't sell the dogs)
Jonathan Adler owns the mother of all foo dogs - check out the monster on his balcony.
