Go out an buy a can of CAT food. Some yummy pate chicken flavors. See if he will eat that (you may want to add a bit of water to keep his fluids up).
If he came home yesterday, and you can't get him to eat anything by tomorrow, they you either need to get to the vet on Saturday... or take him later today.
Puppies HAVE to keep hydrated at the least or go down hill very fast. So you are right to be concerned but make sure you give him a bit of time to perk up and REAL yummy food (which cat food is) to get him interested in eating again.
