Panting is normal in new Moms. The action of the pups suckling helps to contract the uterus so that's why you see the panting.
As for the little one....make sure he gets his share. The easiest thing to do is to pull the larger ones for a few minutes and let the little one have the teats to himself. He doesn't need to be wasting all his energy trying to compete and nurse. Put him on one of the rear teats and let him get his fill. Do this until he's big enough to eat with the others without getting pushed off. |
