I think it's from the marrow too Copperbelle, but he's never had diarrhea from marrow before and we give him a rec bone once every week. I'm happier that he is having diarrhea than not having any poops at all because then I'd really be worried about a blockage, so in that sense the diarrhea is a good thing
I didn't know that diarrhea from marrow would last so long though
I always thought they may have a few loose stools the next day but that everything would return to normal after that. I guess I'll just wait a bit longer. We already asked our vet about it on Saturday and he said he wasn't too worried provided that Barkley is behaving the same way as usual and that he's pooping.
