The Verdict

Toxic - never feed to dogs or cats

What It Is

A common kitchen vegetable (and a hidden powder in many foods).

WTF Fact

Onion - raw, cooked, powdered or dehydrated - damages pets’ red blood cells and causes Heinz-body anemia in both dogs and cats. The sneaky risk isn’t a whole onion; it’s onion POWDER hidden in broths, table scraps and some baby foods. Any amount in a pet food’s ingredient list is a red flag.
