Is Autumn Fern toxic to dogs?

Dryopteris erythrosora

Mildly toxic to dogs

Mildly. The ASPCA lists autumn 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. Dryopteris erythrosora is not individually listed in the ASPCA toxic or non-toxic plant database, and no member of the genus Dryopteris appears on either ASPCA list. The non-toxic Boston fern is a different genus (Nephrolepis), so we cannot infer safety from it. Treat autumn fern as mildly toxic and verify with your vet before allowing pets to chew it.

What to do if your dog ate autumn fern

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

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