He could have eaten chocolate or other food that disagrees with all dogs. It could be food poisoning from eating animals that had been dead a while.

I think you see the vet. My dog had a problem with his stomach on an allergy bases. It made him look bad on the outside too. At first they throw up because they ate something bad. But later if he continues to throw up it means that he has a stomach problem or an allergy attack.
