hi there just browsing around the forums can i suggest that you get in touch with oscar pet foods these are great not used them myself but know alot of people that do, they will chat to you about your dogs skin problems and any other problems they may have including their stools.they recomend what will work for you because most skin problems and stool problems are to do with what you feed your dog.i know of one lady who spent a fortune on dog food from the vets that they recomended and it didnt make any diffference what so ever they used oscars now her dog is alot better check out their website and give them a call.hope this helps
