Can Dogs Eat Onion?

✗ Not Safe for Dogs

Overview

Onions are a common kitchen ingredient but are toxic to dogs. They contain compounds that can cause serious health issues, making them unsafe for canine consumption.

⚠️ Warning:

Onions contain thiosulfate, which dogs cannot digest. This compound causes oxidative damage to red blood cells, leading to hemolytic anemia. The toxic dose is approximately 15-30 grams per kilogram of a dog's body weight, but even smaller amounts can be harmful, especially with repeated exposure.

Benefits

There are no known health benefits to feeding onion to dogs that outweigh the risks.

Risks & Precautions

Onions contain thiosulfate, which is toxic to dogs and can lead to hemolytic anemia, a condition where red blood cells are destroyed faster than they can be made. Symptoms of onion toxicity include weakness, vomiting, diarrhea, and breathlessness. All forms of onion, including raw, cooked, powdered, or dehydrated, pose a risk. Even small amounts can be harmful, especially if consumed over time.
