Is River Water Fern toxic to dogs?

Blechnum spicant

Mildly toxic to dogs

Mildly. The ASPCA lists river water 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. Blechnum spicant is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, and the genus Blechnum is not a confirmed ASPCA entry. Although most true ferns are regarded as non-toxic, we treat this species as uncertain: discourage pets from chewing it and verify with a vet before assuming it is pet-safe.

What to do if your dog ate river water fern

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

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