Poor puppy. That looks like digested food that he vomited up. He may have eaten something that he shouldn't have. Therefore I would try to fast him for 12 hours and then offer him small amounts of boiled chicken and plain rice. If he is still vomiting, lethargic, or has lack of appetite and diarrhea, then I would be concerned he may have either intestinal parasites or has contracted the deadly parvovirus. It is best to have him seen by your local veterinarian if he is not getting better. Hopefully he just got into something he shouldn't have and will show improvement within the next 12 to 24 hours. Best wishes with your puppy Mac and I hope he does get better soon.
