Safety status
What this means for your dog
Dogs — toxic. Black Calla's insoluble calcium oxalate crystals release on chewing and immediately sting a dog's mouth, tongue, and throat. Dogs are more likely than cats to take a large bite before backing off, so a single chew can produce a dramatic foaming-and-pawing reaction even though serious systemic toxicity is uncommon.
What to watch for
Most common: foaming at the mouth, pawing or rubbing the muzzle on the floor, vocalizing in pain, and vomiting. Watch for swelling of the lips or tongue, difficulty swallowing, and refusal of food or water. Rarely, upper-airway swelling can compromise breathing.
Time window
Oral burning starts within minutes of the bite, since damage is from physical crystal injury rather than absorbed toxin. Most dogs recover within 24 hours with supportive care; visible oral swelling can take 1–2 days to settle.
When to call the vet
Call your vet or the ASPCA APCC (888-426-4435) right away if drooling is persistent, your dog is retching, the mouth or tongue looks swollen, or breathing changes. Severe oral swelling or any breathing trouble means call now, not later.
First aid at home
Per Pet Poison Helpline, do not induce vomiting at home and do not give hydrogen peroxide without first speaking to a poison control specialist or veterinarian. Wipe any loose plant material from the mouth if you can do so safely, and bring a piece of the plant for identification.
