Is Dark Mullein toxic to dogs?

Verbascum nigrum

Mildly toxic to dogs

Mildly. The ASPCA lists dark mullein 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. Verbascum nigrum is not individually listed on ASPCA's toxic or non-toxic plant lists. Like other Verbascum species, it contains iridoid glycosides and aucubin, and seeds contain rotenone-related compounds. Mild gastrointestinal irritation is possible if ingested in quantity by pets or people. Traditional use of the flowers in herbal tea preparations exists, but raw plant material should not be consumed without professional guidance. Regarded as low overall toxicity risk.

What to do if your dog ate dark mullein

  1. Remove any plant material from your dog's mouth and move dark mullein 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 dark mullein to the appointment so it can be treated correctly.

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