Why Are Cooked Onions Bad for Dogs?
Cooked onions are harmful because they contain thiosulfate, which can cause oxidative damage to red blood cells in dogs. This can lead to hemolytic anemia, a condition where the body destroys red blood cells faster than it can produce them. Symptoms can range from lethargy and weakness to more severe impacts like collapse and organ failure.
How Much Cooked Onion Can Dogs Eat?
Ideally, dogs should not eat any cooked onions. Even small amounts can pose a risk, especially in smaller breeds that have lower thresholds for toxicity. If your dog consumes any, monitor them closely and contact your veterinarian immediately for advice on the next steps.
Common Misconceptions
One common misconception is that cooking onions makes them safe for dogs. This is false. Cooking does not remove the harmful compounds that make onions toxic. Another myth is that small amounts or feeding onions infrequently won't cause harm. However, the cumulative effect can lead to serious health issues over time.

- Chives: Though milder in flavor, chives also pose a risk of toxicity to dogs.
- Leeks: Part of the same plant family as onions and garlic, leeks can also cause serious health problems for your furry friend.

How to Treat Cooked Onion Poisoning in Dogs?
Your veterinarian may initiate treatment by inducing vomiting or administering activated charcoal to prevent further absorption of toxins. Intravenous fluids could be used to flush toxins out, and blood transfusions might be needed in severe cases of anemia. Treatment could require days of hospitalization depending on the severity.
