What to watch for

• Peas Moderate risk
  Peas add plant protein, starch and fiber. The FDA has been investigating reports of heart disease (DCM) in dogs eating diets high in peas, lentils and other legumes, often grain-free. No cause has been proven, but it is worth knowing when legumes sit near the top of the list.
• Pea protein Moderate risk
  Protein extracted from peas, used to raise the protein number without more meat. The FDA has been investigating reports of heart disease (DCM) in dogs eating diets high in peas, lentils and other legumes, often grain-free. No cause has been proven, but it is worth knowing when legumes sit near the top of the list.
• Sweet potato Low risk
  A starchy root vegetable that supplies carbohydrate, fiber and beta-carotene. Potatoes and sweet potatoes were common in the grain-free diets reported in the FDA DCM investigation.
• Potatoes Low risk
  Cooked potato is a digestible starch used in many grain-free kibbles. Potatoes were common in diets reported in the FDA DCM investigation.
• Potato protein Low risk
  Protein extracted from potatoes, used to raise the protein number in grain-free foods.
• 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.
• Salt Low risk
  Salt supplies sodium and chloride, which dogs need. Pet foods use small amounts; high salt is mainly a concern for dogs with heart or kidney disease.
• Copper sulfate Low risk
  A source of copper, an essential trace mineral. Some breeds accumulate copper in the liver, and vets have raised concern that some dog foods supply more than dogs need.

What it does well

• High protein 42.7%
  30% or more on a dry-matter basis.
