Puppy 12 weeks won't eat or drink is being sick and just sleeps called out vet he was kept overnight and put on a drip they said he had perked up next day charged 130 pound and sented him home when home still would not eat or drink still had all the same things wrong with him am taking him back to vet now but am afraid they are not helping him what can I do

I would call another vet. Has your pup been vaccinated for Parvo? Unfortunately there is so much for us to guess at. The most important thing is to keep a sick puppy hydrated. I am shocked the vets sent him home with out him drinking on his own. I wouldn't stress too much over the food, but he needs to keep hydrated.

I agree both on the hydration and another vet.
