Euphorbia pulcherrima
Short answer: Poinsettias are mildly toxic to dogs and cats. The sap irritates the mouth and stomach and can cause vomiting, but the ASPCA says their toxicity is generally overrated.
Toxic principle: Irritant sap.
The ASPCA lists poinsettia as toxic to dogs, cats and horses, but describes it as “generally over-rated in toxicity.” Most pets that chew a leaf only get a mild upset stomach.
The ASPCA describes poinsettia toxicity as generally overrated: the usual effect is irritation of the mouth and stomach, sometimes with vomiting. Call your vet if your pet keeps vomiting or seems unwell.
