UPDATE FROM FOSTER CARE:
BethAnn has a vast amount of milk. Her puppies are rolly-polly. At 3.5 weeks they were barely walking, mostly just lying in their little bed waiting to be fed. At 4 weeks I forced them to leave their bed so they would start to do some walking and they began to eat a wee bit on their own. At 4 weeks they are not walking as well as Victoria’s were walking at 3 weeks. Each puppy weighs between 4 and 5#.
Remember, these puppies are biological siblings but being raised by different mothers. Ah, the old nature/nurture argument. What remains, is which is better, huge slow moving but happy puppies or active slim puppies, who also appear to be happy, though motivated. :-)
