just a thought but try changing his JWB,i used to feed my dog on this but he was so loose on it , i changed it, he is now on natures diet with pets at home own brand adult complete dry food. And he has had no problem, more firm poo and can now clean it up!! I also had an interesting chat with chap at local pet shop, i didnt realise JWB is part of pedigree and think the quality of the food has been changed. He has had lots of people saying how there dogs used to be fine on JWB but now are having very runny poos. So just an idea. Hope he improves soon.
