Is this just one puppy you are talking about, or several in a litter? Have the pups been checked over by a vet since they were born? Are you bottle feeding the pup/s? Milk coming out the nose in bottle-fed pups can be a sign of over-feeding.
If the pup is thriving, feeding well and putting on weight, he/she is probably ok, but it might pay to get a vet to check puppy over to make sure it's nothing more. Occasionally pups are born with a very soft palate or a palate that is not fully formed (like a human cleft-palate), which makes it difficult and sometimes impossible to feed properly without inhaling milk into the lungs, making puppy cough and sneeze, and have milk come back through the nose.
Best get a vets opinion, just to have peace of mind that all is going well.
Enjoy your pup/s!!
