My dog ate spear-leaved arrowhead vine — what to do

Step by step

  1. Take spear-leaved arrowhead vine 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 spear-leaved arrowhead vine — FAQ

Is spear-leaved arrowhead vine poisonous to dogs?

Yes — the ASPCA lists spear-leaved arrowhead vine (Syngonium hastifolium) as toxic to dogs. All Syngonium species contain insoluble calcium oxalate crystals throughout their tissues. If chewed or ingested by cats, dogs, or humans, crystals cause immediate oral irritation, burning, excessive drooling, vomiting, and difficulty swallowing. ASPCA lists arrowhead vines (Syngonium podophyllum) as toxic to dogs and cats; S. hastifolium shares the same toxic principle as an Araceae aroid.
