Is Log Fern toxic to dogs?

Dryopteris celsa

Mildly toxic to dogs

Mildly. The ASPCA lists log 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 celsa is not individually listed in the ASPCA toxic or non-toxic plant database; some Dryopteris species are flagged as potentially irritating to pets by non-ASPCA sources. Until authoritative confirmation is available, treat as mildly toxic and keep away from cats and dogs.

What to do if your dog ate log fern

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

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