Signs to watch for
Oral irritation, intense burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
Symptoms are generally localized to the mouth and gastrointestinal tract. Please contact your veterinarian or a pet poison control center if ingestion is suspected.
First aid at home
Wipe out the mouth with a clean damp cloth to remove visible plant fragments and offer cool, fresh water to rinse the oral tissue. Do not induce vomiting. Skip milk, peanut butter, vegetable oil, and salt — Pet Poison Helpline lists these as ineffective and sometimes harmful home remedies. Then call your vet.
What to watch for
Pawing at the mouth, head shaking, and a sudden distressed expression are usually the first signs. Heavy drooling or foaming, lip or tongue swelling, and a hoarse or muffled bark can follow if the airway is irritated. Vomiting, retching, and a temporary refusal to eat or drink are common; persistent severe vomiting is less typical for this plant.
Time window
Burning starts within seconds of biting the plant; drooling and oral irritation typically peak within the first 30 to 60 minutes. Most dogs settle within 12 to 24 hours with supportive care.
When to call the vet
Call right away for any swelling of the lips, tongue, or throat, audible changes in breathing, or persistent retching. Otherwise contact your vet or the ASPCA Poison Control hotline (888-426-4435) for drooling that does not settle within an hour, or if your dog refuses water for more than a few hours.
What this means for your dog
Dogs that bite into a calla lily get an instant dose of needle-like calcium oxalate crystals — sharp enough that most spit the plant back out before swallowing much. The reaction is dramatic but almost always limited to the mouth and stomach; systemic poisoning and kidney failure are not part of this plant's profile.
