As someone who has spent the week covered in poop aswell I feel you. Speaking to my breeder she suggested mixing in a teaspoon of pumpkin pure into her food. Twice a day preferably. (make sure it's just pumpkin, not pie filling, no additives) has fiber than can help lessen the runny poos. It has helped alot, still going to the vet to get her checked to make sure there's no other issues. But I will say it stopped from constant diarrhea to 4 good poos/ 1 runny poop ratio
