Why it’s harmful to dogs
Poinsettias are the red, pink or cream holiday plants that sell by the truckload every December. The colorful "flowers" are actually leaf-like bracts, and the plant leaks a milky white sap when a leaf or stem breaks.
That sap is the issue. The ASPCA lists poinsettia as toxic to dogs because of its irritant sap, but it says the plant is generally overrated in toxicity. Pet Poison Helpline agrees and rates the effect on dogs as mild, with diterpenoid euphorbol esters and soap-like compounds irritating the mouth and stomach. VCA Animal Hospitals say poinsettias do not usually cause significant poisoning.
Most incidents involve a dog chewing a leaf off a gift plant on a low table or the floor. Skin contact with the sap can cause redness, swelling and itching, and eye exposure can rarely cause mild irritation.
If your dog ate poinsettia
Clear any leaf from your dog's mouth and move the plant out of reach. Watch for drooling, vomiting and a sore tummy. There is no antidote, and Pet Poison Helpline says signs are usually self-limiting and rarely need treatment unless they are severe or persistent.
Call your vet, or ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply), if signs last longer than a day, if your dog vomits repeatedly, or if your dog ate a lot. VCA suggests calling if signs last over 24 hours or are severe. Outside the US, call your local emergency vet. Don't try to make your dog vomit at home.
Keeping your dog safe
Put poinsettias on a high shelf or in a room your dog can't enter during the holidays, and sweep up dropped leaves. Hanging baskets and tall plant stands work well if your dog counter-surfs.
If you'd like seasonal color with no worry, a blooming Christmas cactus or an orchid is a friendlier choice. Keep other holiday plants like holly and mistletoe out of reach too.

Frequently asked questions
Are poinsettias deadly to dogs?
No. The ASPCA says the plant is generally overrated in toxicity, Pet Poison Helpline rates it as mild for dogs, and the Merck Veterinary Manual says the sap causes drooling and vomiting but not death. It is still on the toxic list, so keep it out of reach.
Can poinsettia sap hurt a dog's skin?
Yes, Pet Poison Helpline says sap on skin can cause redness, swelling and itching. Call your vet if irritation persists or gets worse.
When should I call the vet after my dog eats poinsettia?
Call if signs are severe, repeat, or last more than about a day. VCA suggests calling if signs last over 24 hours.
