Diarrhea can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc. Drooling is usually a sign of nausea, but can also involve bad teeth or an injury or tumor in the mouth. I would fast Jacob for 24 hours and then put him on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the diarrhea or if your dog gets lethargic, heneeds to see a veterinarian for an exam as there may be something more serious such as an infection going on.
