Can dogs eat Onion?
Onion（玉ねぎ）
Do not feed
Never give this to dogs. Cooked onion, its broth, and onion powder are all treated the same.
If your dog ate this
Confirm what your dog ate, how much, and when.
Call your regular clinic; after hours, contact an emergency animal hospital.
What kind of food is this?
A vegetable in the allium family. The organosulfur compounds in alliums can oxidatively damage a dog's red blood cells, which can lead to hemolytic anemia.
The compounds survive cooking and leach into soups and stew broth. Onion powder is treated the same way.
Symptoms may appear not right after eating but some time later.
Avoid the whole allium family
Onions, green onions, nira (garlic chives), and garlic all belong to the allium family and carry the same family of compounds.
Powdered forms such as onion powder are treated the same way.
