Is Cinnamon Fern toxic to dogs?

Osmundastrum cinnamomeum

Mildly toxic to dogs

Mildly. The ASPCA lists cinnamon 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. Cinnamon fern (Osmundastrum cinnamomeum) is not individually listed on the ASPCA toxic or non-toxic plant database, and online sources conflict, so it cannot be asserted as pet-safe. Treat with caution and verify with a vet; assume only mild, self-limiting GI upset is likely from chewing, but do not rely on a confirmed-safe status.

What to do if your dog ate cinnamon fern

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

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