Poinsettias are considered only mildly toxic to dogs, not highly poisonous or usually fatal.
How dangerous they are
Most veterinary and pet-care sources agree that poinsettias rarely cause more than mild, self-limiting illness in dogs if eaten. The main risk comes from the plant’s milky sap, which contains irritating compounds rather than strong systemic toxins.
Possible symptoms in dogs
If a dog chews or eats poinsettia leaves or stems, typical signs include:
- Mild vomiting, drooling, and sometimes diarrhea.
- Irritation of the mouth, and occasionally mild skin or eye irritation where the sap contacts skin.
These effects are usually short-lived and not life-threatening, especially if only a small amount was ingested.
What to do if your dog ate one
For most dogs, home care is enough:
- Gently remove any plant material from the mouth and offer water to rinse and drink.
- Monitor for vomiting, diarrhea, drooling, or signs of discomfort over the next several hours.
Contact a veterinarian or a pet poison helpline promptly if your dog:
- Ate a large amount
- Is very young, elderly, or has other health problems
- Shows repeated vomiting, severe diarrhea, lethargy, or eye issues.
Safety tips around poinsettias
To reduce risk:
- Keep poinsettias where your dog cannot reach or chew them, or choose pet-safe alternatives.
- Remember that some other holiday plants, such as mistletoe and certain types of holly, can be more dangerous to dogs than poinsettias.
