Just like humans, pets can vomit for many many reasons. It can be something more minor like a bacterial infection or it could be something potentially fatal like parvovirus (if your puppy is not properly vaccinated) or an intestinal blockage. I recommend to play it safe and have Princeton examined by the veterinarian tonight. Puppies who don't eat may run the risk of having low blood sugar or dehydration. It's always best to play it safe. I hope it's nothing too serious and please feel free to post any additional questions.
