about to shed or something else

[paroxysm]

my bp is confusing me. i thought he was going to shed - his belly was pink and his skin was loose.
his eyes were cloudy but they were also deflated and a bit red.
if he is shedding, he is about two weeks in.

but when i looked closer i realized he seems to be very dehydrated.
he's refused f/t food for three weeks even though he was eating with the breeder
i can clearly make out his spine and the different vertebrae.
he is a few months old and around 75 g

any advice? i don't know what to do.
