I fed Bobby Hill's Science Plan for the first year or so. He trived on it, everyone we met would comment on the condition and the shine of his coat. I tried switching to a few other quality brands, but they all seemed to result in looser poos so kept returning to Hills. Then, following many recommendations here, I tried Millies Wolfhart, and there's been no looking back. Initially he was on their countryside mix, now he's on riverside. For most people it's available by mail order only, but the delivery service is fantastic, and you can choose to have it delivered to a local pickup points if that's more convenient.
