We have fun too. Our play has just truly begun. We are 4 days behind the Stormy pups but one day you won't notice a difference in skills. Four days is a lot at this stage but at 4 and 5 weeks, not so much.
The pups are now being weighed in the morning. I was weighing twice a day. gains are on an average 1 ounce plus a day. One of the girls has tiny features. She is the smallest now and will most likely be the smallest in adulthood. You can usually tell not by weight but by bone density and how small the facial features are. The rest of the pups are 5 plus ounces heavier.
I am going to try to get them out of the whelping box this weekend but I have a heavy grooming schedule. We shall see. If not this weekend, Tuesday on my day off from grooming.
