Was this pup given kennel cough (aka bordetella) vaccine? If yes, this vaccine can actually cause kennel cough - which can then progress to pneumonia, esp in puppies. KC/pneu can take several weeks to treat in a puppy. Pneu in puppies is very concerning (as you've seen) bc it can be fatal. If you think your vet is not treating this aggressively enough - I'd go to another vet where they have 24 hour care, in case he needs to be kept there.
Really glad to see his appetite is back, as that's so important! Please, keep us posted on this little guy.
