So sorry to hear that Bubu is not feeling well! Puppies are very prone to intestinal parasites, and depending on which vaccines they have received, viral infections such as parvovirus. Bubu may have also eaten something he should not have which has blocked his intestinal tract or was toxic. He should be seen by a veterinarian as soon as possible as he is likely to become dehydrated very quickly as he loses fluids from vomiting and having diarrhea and not eating/drinking. His veterinarian will likely need to run some tests including blood work, a fecal exam, and take x-rays to determine the cause and prescribe medication to treat the condition. I hope Bubu feels better soon!
