Can Dogs Eat Leeks?
✗ Toxic : Dangerous
Same family as onions/garlic. Toxic to red blood cells.
Leeks are highly toxic to dogs and belong to the allium family, like onions and garlic. They contain thiosulfates, compounds that damage red blood cells and cause haemolytic anaemia. Even small amounts are dangerous, and ingestion requires immediate veterinary treatment. Symptoms include lethargy, weakness, pale gums, dark urine, vomiting, and collapse, often appearing 24-48 hours after consumption. The toxin accumulates in the body, meaning repeated exposure is especially hazardous. All plant parts are toxic, including the white bulb and green tops. Keep leeks and dishes containing leeks completely away from dogs. If ingestion occurs, contact your vet or emergency clinic immediately, providing the amount consumed and time. Early treatment significantly improves prognosis.
Why Leeks Is Dangerous

What To Do If Your Dog Eats Leeks
Contact your vet, especially if your dog has eaten leek-containing food such as soups or stews.
