Skin shedding on 2 week old puppies normal?

[chapple83]

Hey guys. I'm a first time dog owner and I need some help. I have two Siberian Husky/Golden Retreiver puppies that are only 16 days old. (The mom got hit by a car right after they were born.)

Anyways, both puppies have skin peeling off underneath on their bellies and on their hind legs. It's quite a bit. I don't know if this is normal in newborns or if there is something wrong and I'm getting kind of worried. Any help will be greatly appreciated.

Also, the pads on their feet look like they have been bleeding. There is dried blood in the crevaces on the bottoms. Should I be concerned?

Thanks for any help or advice you could give.
