Hi everybody ( that was from dex)

I feed dex TOTW high prairie.. He has been on this since the day I got him. My question is what is a healthy % of protein fat and fiber? I've noticed some of the other high quality foods have a higher % of protein fat but less % of fiber.
Any comments on the negatives of having higher protein and fat?
Is the fat content what most worry about for pancreatitis?
Any thoughts or concerns...
Thanks!
