My 8 week old puppy is bright and energetic but has gone off his food, he had a big meal in the morning a few mouthfuls at lunch and nothing for his third meal, so I need to worry?

Hello. If he's bright and alert and feeling well drinking water no vomiting and no diarrhea I would not be too concerned at this time. But if he refuses to eat tomorrow or shows any signs of lethargy loss of activity vomiting diarrhea, he does need to be seen as soon as possible. Hopefully he'll feel better in a day or so.
