There are several good choices to choose from but since he’s only eaten one food for 3 years, it could take some time (weeks to months) to transition him off, but don’t let that discourage you. Get a good multi-strain probiotic to help seed his gut with a more diverse population since his gut is only used to digestion RC. Since he’s eating grain right now, there are some other good grain products that are gluten free like Nutrisource small/med puppy (yes for your old guy, it’s for all life stages). If you’re confused about that statement, we can discuss it some more. Also there is Nature’s Logic, Nature’s Select Hi-Pro, Merrick Classic, Solid Gold Sundancer, Acana (might have gluten contamination in the oats). For grain free small kibble options, there is Amicus and Instinct (but I wouldn’t try this one yet, it would be too much for him, way too different from RC), Merrick grain free and Nutrisource grain free. I would suggest Amicus or Nutrisource grain free Heartland Select for grain free starters because they are “medium” range. Instinct and Merrick grain free are “high”. Start by adding just 20% of new food to his RC and don’t increase the new food until he has satisfactory output, however long that takes. At his age, I would strongly think about adding canned food to his diet (if you’re not already) or making it the majority of his diet. It is “a step up” from kibble.
