What You Need to Know

It contains calcium oxalate crystals plus additional proteolytic enzymes that amplify the irritation compared to some other oxalate-containing plants. Throat swelling can be significant enough to cause breathing difficulty — particularly dangerous in smaller dogs. Immediate veterinary attention is recommended for any Dieffenbachia ingestion.
