    Is poinsettia toxic to dogs?

    Poinsettias have a reputation as deadly, but they are only mildly toxic. Their milky sap can irritate a dog's mouth, stomach, skin and eyes. The toxic principle is irritant milky sap (diterpenoid esters).

    Toxic dose by dog weight

    There is no reliable numeric toxic dose for poinsettia in dogs, so we don't show a weight-band table — inventing one would be misleading. No numeric toxic dose; toxicity is mild and usually limited to GI irritation. Smaller dogs (toy and small breeds) are generally at higher risk from any given amount.

    Symptoms timeline

    0–2 hours: drooling, licking lips, mild vomiting.

    2–12 hours: occasional diarrhea, mild lethargy.

    12–72 hours: usually fully resolved. If signs persist or new signs appear, call your vet.

    Days later: some poisonings show signs later than this. If in doubt, call your vet.

    • Vomiting is repeated or your dog seems unwell
    • Your dog ate decorations, foil or pots along with the plant
    • You are unsure what or how much your dog ate
    • Your dog is very young, old, pregnant or has heart, liver or kidney disease

    First aid: do's and don'ts

    Do:

    • Move your dog away from the source and remove any remaining material from their mouth if it is safe to do so
    • Keep the packaging, label or a sample/photo of what was eaten
    • Note your dog's weight, the approximate amount and the time of ingestion
    • Call your vet or a pet poison hotline right away

    Don't:

    • Never induce vomiting without veterinary advice — for some substances it causes more harm
    • Don't give salt, hydrogen peroxide, oils or home remedies unless a vet tells you to
    • Don't wait for symptoms if the substance is highly toxic
    • Don't give human medicines to treat symptoms

    How vets treat poinsettia exposure

    Treatment depends on the amount, time since ingestion and your dog's signs. It may include decontamination when appropriate, activated charcoal for some toxins, IV fluids, medications to control signs, and monitoring. Bring the packaging so your vet can tailor treatment.

    Prognosis

    Most dogs treated early do well. The outlook depends on the dose, how quickly care begins, and your dog's overall health. Severe or delayed cases carry a more guarded prognosis.
