Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Your dog appears to be young (under a year) from what I can tell based on the pictures and information you provided. The most likely diseases are as follows: 1. Parvo, a virus that primarily attacks the immune system and intestines of dogs and is very lethal if left without supportive care. 2. Intestinal parasites which can cause intestinal blockage and even anemia (depletion of red blood cells). 3. Other viruses with varying severities. This is not an exhaustive list, just the most common things for a puppy. They will all lead to dehydration and other secondary issues which can all be severe enough to cause death. Whatever the underlying disease, he looks very ill and needs attention from a veterinarian immediately. I would recommend taking him to your nearest emergency veterinary hospital as soon as possible. I hope this helps and your dog gets better!

    Your poor pup! There could be a couple reasons behind his illness, such as an infectious disease, a foreign body, pancreatitis, or eating something rotten. While intestinal worm burdens do cause vomiting, he would have to have a very heavy burden to cause his symptoms. I would have him seen by a vet for this problem. He needs a deworming treatment for the worms, and he should also be examined and treated for the vomiting. I'd take him into the vet first thing in the morning. Best of luck, I hope this helps!
