Great pictures! Keep them coming. I love the mob of puppies. Enjoy getting group shots while you can...I have a feeling they'll be waaaay to wiggly in a few more weeks.
I had a litter of 13 once and it sure took a lot of changing the line from fore teat to rear teat ! Luckily they got her 2 front ones going , so she had 10 . I never had to supplement .
