I am concerned about Tyson feeling so cold. If you have a rectal thermometer, you can take his temperature. Normal is 100-102. If it is low, he should see a vet immediately. Also, you can place a small amount of honey or caro syrup on his gums in case he is hypoglycemic. Other potential causes for his illness include intestinal parasites (even if he was already dewormed once, they are still possible), GI blockage, bacterial or viral infection, food intolerance, among a few other possibilities. Any puppy that is lethargic or has vomiting and/or diarrhea should see a vet if the symptoms last more than 24 hours as they can get dehydrated very quickly.
