You have to do it now before they get their fur. To me it looked like little pin pricks. You have to pick them up, with clean hands and turn them over and have a look. The nipples should be on the hips kind of area on the belly (can't think of how else to describe it!)

The males will have nothing at all.

Sorry for the 100 questions but what will you do with Sage and Jade if you give the pups away?
