Yes, your vet should be able to help you. In the meantime, a lot of people don't realize that besides feeding and keeping young ones warm, is the need to help them eliminate. Working in a rescue shelter (both for wild animals and one for cats) we have many encounters with very young animals. This might sound a little gross, but after the baby eats, the mamma usually licks the belly of the baby to get it to eliminate. They don't know how to do it themselves. What we do in the rescues is take a very soft napkin and lightly swipe their lower area to stimulate them.

Be sure to keep us posted on their progress!! We love puppies!!!
