Q. My dog is throwing up alot anhd not eating and he just started today and he was eating fine the night before

A. I would recommend to take him to your veterinarian for a check up as puppies can get dehydrated pretty quickly and especially if he is lethargic would need a consultation as soon as possible. Different form of gastroenteritis ( dangerous if not vaccinated) can cause that. If he is bright and keep drinking you could withold food for the next 4 hours and then start feeding him back again with small portions of digestible diet like chicken and rice ( boiled).
