I'm a bit confused about entropion 'righting itself' unless the puppy had loads of wrinkle (as in baby Bassets) which, as the head develops, may mean there's not quite as much surplus skin across the head?
For me, however, any discharge (yellow would be more likely to suggest infection) would tell me something isn't right - and it could be the entropion actually hasn't righted itself? And the third eyelid reacting also says the situation isn't right.
As anything to do with eyes I regard as 'an emergency' I'd have another go at your vet, or find another!!
I took my girl back to have her leg checked and redressed this morning and actually went in with her for the first time (waiting area only, with a mask on) as she didn't want to go with the vet on duty this time.
I don't understand really why your vet is only accepting emergency patients ... things are freeing up, little by little now.
