Hi, I'm Ari and I am currently raising an orphaned puppy, he's 2-3 weeks has been fed substitute formula and mashed up dryfood since he doesn't have teeth yet and that's what the vet said. It's late at night and he has yellow diarrhea, can't go to the vet till tomorrow, he's as active as usual, still eating, thanks for the help

Odie is so cute! Given that he's active as usual, I'd just keep an eye on him for now, and have him seen by a vet in the morning. If the diarrhea gets worse, he stops eating, and/or becomes very lethargic, then I would rush him into an ER vet. Best of luck.
