My sick doggies

Both Porter and Sadie are sick. Not only do they have diarrhea, and accidents in the apartment overnight, but they're very lethargic. On our second walk of the day yesterday, Porter laid down on the sidewalk after only 15 minutes outside. It was muggy and hot but he's never done that so soon into a walk before. We fasted them for a whole day two days ago and the symptoms got better, but made the mistake of feeding them yesterday. Today they're going to eat a mixture of applesauce, chicken broth and pumpkin to try and get them back on track.
