Sick again

I posted here not too long ago about my puppy having extreme soft and liquid stool. He was getting better (stool has hardened) but this morning he woke up like this.

Every 5-10 minutes I’m cleaning out his eyes with a warm cloth and it’s coming back more gooped and red. He is itching his face and chewing at his back end. I don’t know what else to do or what is causing it.

Anything I can do to calm it? And any ideas what it could be from. He has an appointment on Monday but if it continue we would be taking him to the emergency vet tonight.

- he’s not acting any different apart from his eyes being droopy, mucusy and red.
