Is Croton toxic to dogs?
Croton (Codiaeum variegatum) is toxic to dogs. The agent is diterpene esters in the sap.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What it does, and why
Croton contains diterpene esters in the sap. The compound sits in the sap, so the plant does the most harm when it is broken — chewed, snapped, or pruned. Skin contact can irritate as well as ingestion.
Signs to watch for
Mouth and stomach irritation, vomiting, diarrhea; skin irritation from the sap.
How likely is it, really
Most cases are a chewed leaf rather than a meal. The dose matters: a nibble and a swallowed stem are different events. Volume, and how long ago, are the two things the vet will ask.
Keeping the plant anyway
Height alone does not work with a dog. What actually helps: a room the dog does not have unsupervised access to, a hanging position with no adjacent launch point, and clearing fallen leaves the same day, since a dropped leaf on the floor is the usual culprit. Dogs chew from boredom more than appetite — the fix is usually enrichment, not the plant.
Is it toxic to people?
Yes, mildly. The same compound irritates human mouths and skin, so it is worth keeping Croton out of reach of a toddler and washing your hands after pruning. Serious harm to an adult is very unlikely.

Sources and how we checked
This species is not listed under a name we could resolve in ASPCA's database, so the record above comes from standard horticultural and veterinary references and is marked unconfirmed. We do not present an unconfirmed plant as safe. The full list is at aspca.org.
This is general information, not veterinary advice. Any animal that is actually unwell needs a vet, not a web page.
