Hi, you dont say how old your puppy is and whether she is still eating or not.If only around 8 weeks old, not eating and sickness and runs. I would take her to the vet. They can go down very quickly at a young age. But if you think its just and upset tummy, try warm rice pudding or scrambled egg made with water not milk.We had bred dogs for over 60 years and this food is brilliant for tummy bugs or poorly pups recovering from illness just to get them eating again, they love rice pudding.
