Dog Paws

Hey, I have a question about dogs' paws. Are they always black? Or can they be white/pink? Just wondering:)

I've never seen any white paws, but i've seen brown and black.

Nala has black with pink spots.

I'm pretty sure I've seen dogs with pink paws...not white though..

I've never seen white paws but Kai has pink/black paws.

Angus & Huney's are black, but Roxey has cute little pink and black paws (but only when they're clean:p).
