Is Chain Fern toxic to dogs?

Woodwardia radicans

Mildly toxic to dogs

Mildly. The ASPCA lists chain fern 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. Woodwardia radicans is not individually listed by the ASPCA, and the genus Woodwardia does not appear on the ASPCA non-toxic list. True ferns are generally considered non-toxic, but without explicit ASPCA grounding for this species or genus, treat with caution and verify with a vet; mild gastrointestinal upset is possible if eaten.

What to do if your dog ate chain fern

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

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