What to watch for

• Corn Low risk
  Cooked corn is a digestible source of energy and some protein. It is often criticised but is not a common allergen; its main risk is mould toxins (aflatoxin) when quality control is poor.
• Animal digest Low risk
  A flavor coating made by breaking down animal tissue, sprayed on kibble to make it tasty. When the species isn't named you can't tell what animal it came from.
• Brewers rice Low risk
  Small broken pieces of rice left over from milling. Digestible energy but fewer nutrients than whole rice.
• Corn gluten meal Low risk
  The protein left after starch is removed from corn. It raises the protein number on the label cheaply, but plant protein is less complete than meat protein.
• Pea fiber Low risk
  Fiber from pea hulls. A legume ingredient, so it counts toward the legume load in grain-free foods.
• Fish meal Low risk
  Rendered fish. A concentrated protein, but 'fish' does not name the species, so it is harder to avoid if your dog reacts to a particular fish.
• Natural flavor Low risk
  Flavoring from natural sources. Normally safe, but the term can hide which animal or plant it came from, which matters for allergies.
• Wheat gluten Low risk
  Wheat protein used to bind wet foods and raise the protein number. Less complete than animal protein.

What it does well

• Taurine added
  Cats need taurine in their diet; this label lists it.
