Is Black Seed toxic to dogs?

Nigella sativa

Mildly toxic to dogs

Mildly. The ASPCA lists black seed as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Nigella sativa is not individually listed in the ASPCA Toxic and Non-Toxic Plant database, so a definitive pet-safe rating cannot be given; treat with caution and verify with a vet. The seeds contain thymoquinone, which has been flagged as a concern for cats in larger amounts, so keep significant ingestion away from pets.

What to do if your dog ate black seed

  1. Remove any plant material from your dog's mouth and move black seed out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of black seed to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten black seed, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
