Elvis had been having ear issues, after much trial and error (and cost!) the vet suggested pork mince and potato, it certainly cleared up his gunky ears and his #2's were noticeably a lot smaller and easier to pick up. After 2 months of pork mince and potato I switched to Burns sensitive + (pork and potato) kibble, His ears are still good but his stools are now quite a lump bigger. Same scenario with my other dog Ruby too, although her ears were fine to start with I just gave them both the same food, her stools were a lot smaller on the pork mince and potato diet.
