My dog ate Red-stemmed Sensitive Fern — what to do

Step by step

  1. Take red-stemmed sensitive fern away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My dog ate red-stemmed sensitive fern — FAQ

Is red-stemmed sensitive fern poisonous to dogs?

Yes — the ASPCA lists Red-stemmed Sensitive Fern (Onoclea sensibilis 'Rotstiel') as mildly toxic to dogs. Onoclea sensibilis is reported in several horticultural toxicology references as mildly toxic to cats and dogs; all parts of the plant are considered potentially harmful and ingestion may cause gastrointestinal symptoms including vomiting and diarrhoea. It does not appear on the ASPCA confirmed non-toxic list. Keep pets away from the plant.

How serious is it if my dog ate red-stemmed sensitive fern?

Red-stemmed Sensitive Fern is mildly toxic, so most dogs get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your dog ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Onoclea sensibilis is reported in several horticultural toxicology references as mildly toxic to cats and dogs; all parts of the plant are considered potentially harmful and ingestion may cause gastrointestinal symptoms including vomiting and diarrhoea. It does not appear on the ASPCA confirmed non-toxic list. Keep pets away from the plant. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my dog vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep red-stemmed sensitive fern well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
