Hi was your dog tested for EPI & have you ever used a Digestive Enzyme? when I reed what you have used I see pumkin & the pumkin didn’t help …..Pumkin is high soluble fiber, what % fiber is the Hills light kibble made up of more soluble fiber or more insoluble fiber, email Hills & ask you want the % of the soluble, insoluble & crude fiber in the Light, but were his poos ever firm on the Hills light??? the Hills Z/d vet diet is high in insoluble fiber, it went thru my boy, so my boy needs a kibble & foods that have soluble fibers, not insoluble fibers, my boy did real well on the vet diet Euknauba Intestinal low residue kibble, the fiber is only 1.7% & the Royal Canine Intestinal low fat the fiber is 1.7%
another thing if he’s doing better on the raw, raw doesn’t have much fiber so ur vet may have it wrong, have you seen any other vets that specialise in IBD, I can try & work it out with you….I think ur dog need less fiber…..
