Try the pepto bismal
and a bland diet for a day or two
and see if the dog stops the runs
and the stool will still look very sticky like peanut butter, then start w/soft food, then mixed soft w/hard, and see if the stool get better. Thats what I do....
My soft diet would be cottage cheese mixed w/a good brand soft dog food for 2 days..
But, if there is water,mucos, blood tinge, or very stinch odor, you must go to the vet immediately, for there are many reasons for your symptoms....
