What dog food is he on? If he has no issues why do you want to switch?

Hope these sites help

I lean toward fish based, Zignature or Nutrisca but that is because one of my dogs has environmental allergies and does best on fish as a base.
I have heard good things about Pro Plan Focus Salmon and may try it in the near future.
I avoid potato, not that there is anything wrong with potato, but I don’t think it should be more than 10% of the diet.
Some kibbles are LOADED with potato (cheap starchy filler)
