Is Charming Dieffenbachia safe for dogs?

Yes, Charming Dieffenbachia (Dieffenbachia amoena) is toxic to dogs. It contains insoluble calcium oxalate crystals that cause immediate oral irritation, intense burning of the mouth, tongue, and lips, excessive drooling, vomiting, and difficulty swallowing.

Oral pain typically begins immediately when a dog chews on Dieffenbachia, though signs can occasionally take up to two hours to appear. You may notice your dog suddenly shaking its head, drooling heavily, pawing at its face, vomiting, or refusing to eat. Less commonly, swelling of the tongue or throat can cause noisy or labored breathing, which is a medical emergency.

Remove any remaining plant material from your dog's mouth, then offer something tasty to flush the crystals — milk, canned tuna in water, or chicken broth. Milk is especially effective because oxalate crystals bind to its calcium, reducing pain. Do not induce vomiting unless directed by your vet. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if drooling and pain don't settle within a couple of hours, vomiting is repeated, or your dog won't eat or drink.

Painful effects from Dieffenbachia ingestion usually dissipate within 12 to 24 hours, and most dogs recover fully without significant complications. Go to an emergency vet immediately if you notice any swelling of the face, tongue, or throat, a change in bark, or noisy or labored breathing — these signs indicate airway involvement and cannot wait.
