I have puppies that are 3 weeks old and I am feeding them goat milk like I have done in the past, but I have had one to get sick in a matter of 2 days and it die. I have noticed one of the other puppies is having the same symptoms. What can I do to keep the other puppies from dying?

Why aren't the pups still with their mom? They are not weaning age yet. I had to feed some newborn pups that were found in a river several years ago. We checked with the vet for directions on how to care, he advised infant formula such as Similac and feeding with a bottle. It worked, none died and all turned out pretty healthy. We also had to rub their tummies to make sure they eliminated easily.
