Can Dogs Eat Leeks?

Unsafe for Dogs

Safety Information

Part of the onion family. Toxic to dogs.

Important Notes

Can cause gastrointestinal upset and red blood cell damage.

The Dangers of Leeks

The toxic compounds in leeks, primarily thiosulfates, cause severe oxidative damage to a dog's red blood cells. A dog's body cannot properly digest these compounds, which leads to the destruction of red blood cells in a process called hemolytic anemia. This dangerous condition impairs the blood's ability to carry oxygen, which can lead to organ damage and, in severe cases, death.

Hidden Dangers in Soups and Stews

Leeks are a common ingredient in human foods like soups, stews, and stocks, often used to add a mild onion-like flavor. This is a primary reason why feeding your dog table scraps can be so dangerous. They may unknowingly ingest leeks or other Allium family vegetables that have been cooked into a dish.

Signs of Leek Toxicity

  • Symptoms are consistent with onion and garlic poisoning and may be delayed for several days after ingestion. Be on the lookout for:
  • Vomiting and diarrhea
  • Lethargy and weakness
  • Pale gums
  • Rapid breathing
  • Elevated heart rate
  • Dark, reddish-brown urine

What to Do If Your Dog Eats Leeks

If you know or suspect your dog has eaten leeks, consider it a veterinary emergency. Contact your vet or an emergency animal hospital immediately for advice and treatment.

The Bottom Line

Leeks are firmly on the "do not feed" list. The risk of hemolytic anemia is serious and potentially fatal. Keep leeks and any dishes containing them safely away from your dog.

Emergency Notice

If your dog has consumed leeks, contact your veterinarian or the ASPCA Animal Poison Control Center (888) 426-4435 immediately.

General Feeding Guidelines

Introduce new foods gradually to monitor for allergic reactions or digestive issues.

Treats and human food should make up less than 10% of your dog's daily caloric intake.

Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
