If you shave any animal their skin color is the same as their fur, in some rare instances black fur will have white skin but that's mostly in cats and you can tell that dog has black skin.

I don't know why people are thumbing you down...you're right. Dog's skin is usually the same base color but a lighter shade than their fur. For instance, my dog is a harlequin (black and white spotted) when she had surgery a few weeks ago they shaved her to her skin, and her skin was black in the places where black fur was and white in the places where white fur was. I think anon's just butthurt that he was wrong.

sorry, for white fur, I meant to say "light pink skin"

a polar bear's skin is black

They aren't really white either...

i know they have clear hollow hair but that wasn't my point

Then what was the point?
