Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Oral irritation, intense burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
The insoluble calcium oxalate crystals cause immediate mechanical irritation. If your dog shows signs of distress or has ingested the plant, please contact your veterinarian for professional guidance.
First aid at home
Pull any remaining plant material out of your dog's mouth and rinse the mouth with clean, cool water to flush out the crystals. Do NOT induce vomiting — bringing the oxalate material back up causes additional burning to the esophagus and mouth. Then call your vet or Pet Poison Helpline for guidance.
What to watch for
Sudden pawing at the muzzle, head shaking, and intense drooling within minutes of chewing. Common follow-on signs: vomiting (often bringing up leaf material), reluctance to eat, and visible discomfort around the mouth. Less common but more serious: noticeable swelling of the lips, tongue, or throat, or any change in breathing.
Time window
Onset is fast — minutes to a couple of hours. With basic supportive care, signs typically resolve within 1–3 days.
When to call the vet
Call your vet or Pet Poison Helpline (855-764-7661) for persistent drooling, repeated vomiting, refusal to drink, or any swelling of the mouth. Treat any difficulty breathing, loud or labored swallowing, or collapse as an emergency and go directly to a clinic.
What this means for your dog
Peace lily is not a true lily, and it doesn't carry the kidney-failure risk dogs face from sago palm or grapes. What it does carry is a load of insoluble calcium oxalate crystals — microscopic needles that punch into a dog's lips, gums, and tongue the instant she bites a leaf. The pain and drool are dramatic, but most dogs recover fully with supportive care once the crystals are flushed out.
