My chihuahua ate lunch meat and he is vomiting, urinating uncontrollably, suffering diarrhea, and is panting. His nose is dry and his head is warm. He does not look good at all .. I do not have the money to take him to a vet, what do I do? Can he die?

Yes there is a possibility of death here but doubt if it will happen. The biggest thing here is to keep him drinking lost of water so he wont dehydrate, and the rest will get whats upsetting him out. If he doesn't get better in the next day , you may have to take him to your Vet as he may have gotten into something else besides the lunch meat.  Good luck
