Is Oak Fern toxic to dogs?

Gymnocarpium dryopteris

Mildly toxic to dogs

Mildly. The ASPCA lists oak 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. Gymnocarpium dryopteris is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true fern with no recognised toxic principle, and ferns of this kind are generally regarded as ASPCA non-toxic; because this species is not individually ASPCA-listed, treat it with caution and verify with a vet before assuming it is pet-safe.

What to do if your dog ate oak fern

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

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