Flags on the label
IAMS
- No nutritional-adequacy statement
Purina Pro Plan
- Unnamed animal ingredient ("poultry by-product")
- Synthetic vitamin K3 — questioned safety margin vs natural K sources
- Garlic is an Allium with the same hemolytic mechanism; trace culinary use is common in pet food, so it warns rather than caps — advisor may escalate
