Start with something like AvoDerm Revolving Menu. It’s single protein and “medium” protein. Other “medium” foods are Nutrisource grain free Heartland Select and Seafood Select or PureVita. If budget is not an issue, check out The Honest Kitchen Zeal. It’s grain free, potato free and single protein (fish) but “high” protein or Sojo’s grain free or Natural Balance LID (both single protein, low protein). I would just recommend a simple ingredient food for a few weeks to see if it helps. If she does ok with that type of food, then slowly add a different food and watch for reactions. Also give probiotics. This will help seed the gut with beneficial organisms for better digestion and less gas. Herbsmith has an herbal allergy formula and quercetin is for allergies too. She can always work her way up to a 5 star food. Some dogs just can’t do it right off the bat.
