What breeds of dogs have webbed feet? I was under the impression (or assumption I guess) that only retrievers and water dogs (like Portuguese water dog, etc) had webbed feet....but are there others?

I ask because this darling little girl (her name is Shammy) is at the shelter and while playing with her today I noticed that she has webbed feet!!

(not the best picture of her, I got it off the website, forgot my camera )


But she doesn't look to be mixed with any "water dogs"!!
