It certainly sounds as though Beast is quite sick. Some of the more common reasons for vomiting and not eating in young dogs are a foreign body intestinal obstruction/blockage, parasites and stomach upset from eating inappropriate food. I'm glad to hear that Beast has been vaccinated because this makes diseases, like parvovirus, much less likely. Since he is such a young puppy, he will be more sensitive to the effects of dehydration from vomiting. A vet should examine Beast, possibly perform abdominal x-rays, and institute any necessary fluid therapy and deworming.

    Oh no, poor Man! He could have eaten something rotten causing him to vomit, could have a severe GI illness, may have a foreign body, or could have parvovirus if he isn't fully vaccinated. It's quite serious that he's now throwing up water, so I would take him into a vet immediately. He will quickly become dehydrated from this, and he needs a shot to stop the vomiting and may need IV fluids for hydration. Please take him into a vet now.
