Is Black Spleenwort toxic to dogs?

Asplenium adiantum-nigrum

Mildly toxic to dogs

Mildly. The ASPCA lists black spleenwort 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. Asplenium adiantum-nigrum is not individually listed in the ASPCA Toxic and Non-Toxic Plant database. PFAF notes that a number of ferns as a class may contain carcinogens and thiaminase (a vitamin B-depleting enzyme); until this species is individually evaluated, a mildly-toxic precautionary classification is appropriate. The closely related Asplenium bulbiferum is non-toxic per ASPCA, but cross-species extrapolation is not confirmable.

What to do if your dog ate black spleenwort

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

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