Is Interrupted Fern toxic to dogs?

Osmunda claytoniana

Mildly toxic to dogs

Mildly. The ASPCA lists interrupted 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. Osmunda claytoniana is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, and the genus is not covered, so a pet-safe label cannot be asserted. Treat with caution, as toxicity in cats and dogs is uncharacterised: keep out of reach and contact a vet if a pet ingests it.

What to do if your dog ate interrupted fern

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

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