Why is my new 2-month-old puppy throwing up food after eating?

Hi! I just got a Border Collie last night. He is 2 months old and I woke up to him throwing up. A few hours later I fed him again and shortly after, he threw up a few times. His poop seems normal and his throw up is just his food. What could it be?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If he does not seem lethargic, I would withhold food for 6 hours and then initiate a bland diet as outlined below. If Bernie become lethargic, continues to vomit or develops diarrhea I would strongly recommend that you have a veterinarian examine him to help better determine what the cause could be. I would want to make sure he does not have a foreign body intestinal obstruction from something he ate, parvo virus, etc. Testing such as a parvo test and abdominal x-rays can help rule these out. He may just have a dietary indiscretion from something he ate or a new food / treat you gave him as well. I hope this helps! Please let me know if you have any other questions or concerns and I would be happy to help you out further.
