The pups are often found snuggling. It is wonderful to see. With only 4 days apart, these 2 crews will be able to be put together earlier vs. later. How nice is that? Of course we have to have eyes open and walking and playing going on but we will get there.
I do not see any squinty eyes so it is not time yet for open eyes. The earliest is 10 days and the latest has been 20 days. Open eyes is not an indicator of anything. They happen when they do. All it does is allow them to ass one more sense to their abilities and it usually means exploring starts occurring.
It will come.
