Puppies at 1 week of age

Puppies have now almost doubled in weight, the smaller one has caught up with "big sister" and both weight in the 10 - 11 oz range.  Their heads and bodies have started to fill out and they have started to get a little pigment on their lips.  They  have not yet opened their eyes and spend their days nursing and sleeping.  They crawl to find their mom using their front legs, but still keep their heads down on the bedding surface while crawling.  When sleeping they generally sleep in a "pile" with each other, much like pictured here, to sustain warmth.  When "lost" from their moms they will sometimes "squeek" -- perhaps nature's way of letting mom know where they are.
