to EBN!!! Sorry to hear about Mr. Winston tummy troubles… if I were you I would just go ahead and put him on a bland diet. Rice with boiled chicken or sirloin, and then gradually (over 10 days) introduce him to the new food. I also give my dogs a tablespoon of plain fat free greek yogurt every morning to help with the gas. Pure pumpkin (NOT the pie filling) will usually firm things up, but you said you already had tried that… watch on the treats as well. Try to stick to one protein at a time and watch for allergies.
