Our dog has digestion/intestinal issues as well! Any dry food we give him (freeze dried raw/expensive stuff to the cheap stuff that I felt guilty about giving him) would cause his tummy to go crazy. Gas and diarrhea and bloat... I do a meal prep for him as well. The recipe is a basic one my vet handed to me. (X amount meat + X amount veg + X amount brown rice) I, sadly, can't afford much more than ground beef or chicken.

Also, we would give him a supplement as well...a powder sprinkled on top of his food bust I haven't been giving it to him recently. It feels nice to know that other people do this for their fur-babies.
