Which Christmas Plants Are Poisonous to Dogs?

Vet verified. Written by Corinne Homer, Copywriter. Reviewed by Dr. Linda Simon MVB MRCVS, Team Vet.

Holiday greenery can turn a familiar room into a new sniffing and chewing project. Poinsettia, mistletoe, holly, ivy and amaryllis can all cause problems for dogs, while plant water, fertilizer, sharp needles and edible decorations create separate risks around a Christmas tree.

The safest plan is to identify every plant before it enters the home, keep questionable greenery entirely out of reach and know who to call before an exposure happens. Plant names are often reused for unrelated species, so save the label and a clear photograph.

Which Christmas plants are poisonous to dogs?

Toxicity is not a simple yes-or-no scale. The exact species, plant part, amount, dog's size and current health all matter. Even a plant listed as non-toxic can cause vomiting or diarrhea if enough fibrous material is eaten, and soil, preservatives or decorations may be more dangerous than the plant.

Use the ASPCA toxic and non-toxic plant list for identification, then call a veterinarian or animal poison service for case-specific advice after exposure.

Are poinsettias toxic to dogs?

Poinsettia sap is irritating, but the plant is generally less dangerous than its reputation suggests. Chewing can cause drooling, licking, mouth irritation, vomiting or diarrhea. Sap on the skin can also irritate.

Keep the plant out of reach and collect fallen leaves. An exposure still deserves professional advice because symptoms and the amount eaten vary.

Is mistletoe toxic to dogs?

Yes. Mistletoe can cause gastrointestinal upset, and larger exposures may affect the heart or nervous system. Different plants are sold as mistletoe, which makes guessing from appearance unreliable.

Hang artificial mistletoe if you want the tradition without the plant exposure. If any real mistletoe is swallowed, call promptly rather than waiting for severe signs.

Is holly toxic to dogs?

Holly leaves and berries can cause drooling, vomiting, diarrhea and abdominal discomfort. The stiff, pointed leaves can also injure the mouth. Berries that fall to the floor are especially easy for a dog to grab.

Use a sealed artificial garland or place real holly where leaves and berries cannot drop into the dog's space. Sweep beneath arrangements daily.

Is ivy toxic to dogs?

English ivy can cause drooling, vomiting, diarrhea and abdominal pain when eaten, and plant contact may irritate skin. Trailing vines in wreaths and garlands can fall into reach.

Do not assume that a high wreath is safe if pieces can drop or the dog can reach it from furniture. Choose an artificial alternative when placement is uncertain.

Are lilies toxic to dogs?

Treat unidentified lilies as unsafe and keep them out of any pet home. Toxicity varies by the plant sold under the word lily. Some cause oral irritation or gastrointestinal signs in dogs; lily of the valley can affect the heart. True lilies and daylilies are a life-threatening kidney emergency for cats.

Because mixed bouquets may not identify every stem, the safest choice is to avoid lilies when dogs or cats live in or visit the home. Call immediately after any cat exposure, including pollen contact.

Is amaryllis toxic to dogs?

Yes. ASPCA lists amaryllis as toxic to dogs. The toxic principles include lycorine, and signs can include vomiting, depression, diarrhea, abdominal pain, drooling, appetite loss and tremors. Bulbs are a concentrated and tempting part of the plant.

Store unplanted bulbs like medications: in a closed container inside a secure cabinet. Do not leave a gift bulb kit under the tree.

Is a Christmas cactus toxic to dogs?

ASPCA lists Christmas cactus, Schlumbergera bridgesii, as non-toxic to dogs and cats. That does not make it food. Eating plant material can still cause mild digestive upset, and decorative soil, fertilizer or small pot pieces can add risk.

Confirm the scientific name because common names can be confusing. Keep the pot stable and beyond reach.

What about Christmas rose?

Christmas rose is not a rose. It is hellebore, and ASPCA lists it as toxic. Drooling, abdominal pain, diarrhea, colic and depression can occur. Do not confuse it with the non-toxic Christmas cactus.

Can you have a real Christmas tree with a dog?

Fir, pine and spruce trees are generally considered low in plant toxicity, but the setup is not risk-free. Needles can irritate or injure the mouth and gastrointestinal tract, oils and sap can irritate, and a tree can topple if climbed or pulled.

Anchor the tree to a wall stud or stable point, use a wide covered base and block access with a sturdy gate. Sweep needles daily and keep the lowest branches free of edible or fragile decorations. Read our complete guide to Christmas trees and dogs.

Pine needles

Needles are sharp and indigestible. A few may cause irritation; a larger amount can create more serious gastrointestinal trouble. Vacuum or sweep them before the dog enters the room and inspect long coats and paws after contact.

Tree sap and oils

Sap can stick to fur and paws, then be swallowed during grooming. Tree oils may irritate the mouth or stomach. Prevent licking and ask the veterinarian how to remove sticky material safely. Do not use solvents or essential oils on the dog's skin.

Tree water and fertilizer

Standing tree water can collect sap, bacteria, preservatives or fertilizer. Cover the reservoir completely and provide fresh drinking water elsewhere. Never add fertilizer, sugar, aspirin or another tree additive where a pet could drink it.

Edible decorations

Chocolate, raisins, xylitol-containing candy, salt-dough ornaments and strings of popcorn do not belong on a dog-accessible tree. Ribbon, hooks and tinsel can become foreign bodies. Use large fabric or shatter-resistant ornaments above tail height.

Are artificial Christmas trees safe for dogs?

An artificial tree avoids sap and falling natural needles, but it can still topple, shed plastic pieces or expose electrical cords. Stable anchoring and a barrier remain useful. Inspect older trees for loose wire ends and flaking material before assembly.

Is fake snow toxic to dogs?

Artificial snow products vary. Some may irritate the mouth, lungs or stomach, and the label may not provide enough information to judge a swallowed amount. Avoid flocked branches within reach and keep the package for poison-control review.

If powder becomes airborne during setup, move pets to another room and ventilate according to the product instructions. Do not let a dog lick fallen flocking.

Pre-lit artificial trees introduce another concern: damaged wire, loose bulbs and coin batteries. Route cords through rigid protectors, block the outlet area and unplug lights when supervision ends. A swallowed battery or bite into a live cord is an immediate veterinary emergency, even when the dog appears normal.

How to protect a dog from holiday plants

1. Inventory every live plant, bouquet, wreath and bulb kit.
2. Photograph the label and scientific name.
3. Use closed rooms or fixed barriers, not verbal commands alone.
4. Check for fallen leaves, berries, needles and soil each day.
5. Keep fertilizer and plant-care products in a locked cabinet.
6. Ask guests not to bring unidentified plants.
7. Save veterinarian and poison-control numbers in every caregiver's phone.

Provide an appropriate retreat, water and a safe activity away from the display. If a dog repeatedly tries to reach the plants, remove the plants rather than escalating punishment.

Recheck the setup from the dog's point of view after furniture, gifts and guest coats arrive. A chair can become a step to a high display, and a trailing tablecloth can pull an arrangement down. Safe placement has to survive the way the room is actually used.

What to do if your dog eats a plant

1. Move the dog away and prevent further exposure.
2. Remove loose material from the mouth only if you can do so safely.
3. Photograph the plant, label and remaining material.
4. Estimate when and how much may have been eaten.
5. Call your veterinarian, emergency clinic or ASPCA Animal Poison Control Center at 888-426-4435.
6. Follow the professional's instructions and bring the plant information.

Do not induce vomiting or give milk, oil, salt, charcoal or a home remedy unless a veterinary professional specifically instructs you. Some substances cause more harm on the way back up, and aspiration is possible.

Emergency warning signs

Seek urgent care for trouble breathing, collapse, seizures, marked weakness, tremors, repeated vomiting, severe diarrhea, abdominal swelling, abnormal heart rate, pale or blue gums, disorientation or inability to stand. Do not wait for symptoms after a known high-risk exposure.

Keep other holiday hazards separate

Plant safety is only one part of the room. Secure cords, candles, batteries, medications, trash, gifts and rich food. Review our room-by-room Christmas dog-proofing guide and Christmas dinner safety guide.
