Onions are toxic to dogs, and any amount can be concerning, but the risk increases with the quantity ingested relative to your dog's weight. For a 20-pound dog, even a small amount of onion can be harmful, so monitoring for symptoms is important.
- Lethargy or weakness
- Gastrointestinal upset such as vomiting or diarrhea
- Pale gums
- Increased heart rate

Onions contain compounds called thiosulfates which can damage your dog's red blood cells, leading to hemolytic anemia. This condition can be serious if not addressed quickly. If you notice any symptoms or are uncertain about how much onion your dog ingested, it’s best to consult a veterinarian immediately.
