You have every right to ask the vet to give explain excatly what is going on with your new puppy. I am so sorry he is sick. Keeping your baby for that long of time in the hospital is going to be very expensive, and this is why I was really worried that he was seriously ill. It's been my experience that Vet's only keep animals for only as long as the animal needs to stay, and only when the animal is very sick
The vet is supposed to tell the owner what is going on and why it is neccessary to keep the puppy in the Hospital and what knind of treatment the pup will be recieving. My vet gave me a paper and it had all the tests , and prices estimate on it, when Suzi was going to need to be in the Hospital. He told me everything , and what to expect, and if she were to become sicker what they would do for her.
My thoughts and prayers will be for Munchie today. I feel bad you just brought him home, and he is not well. If you had a contract with you breeder, I would certainly be in contact with her as well.
