Christmas Dog Safety: What's Actually Dangerous and What to Do

Dog Ate Something at Christmas? Start Here

Several toxins act on a delay, from 6–12 hours for chocolate signs to 24–72 hours for raisin-related kidney failure (Merck Veterinary Manual), so a dog that seems fine now may not be.

1. Stop the exposure and keep the packaging or recipe.
2. Call now. Don't wait for symptoms: contact your veterinarian, or your nearest emergency vet or an animal poison control center right away.
3. Have details ready, but don't delay the call: what it was, how much, when, and your dog's weight; for a wrapped gift, find out what was inside (Pet Poison Helpline).
4. Don't make your dog vomit or give home remedies unless the vet or poison control team says to; hydrogen peroxide can damage the esophagus, stomach and intestines (Pet Poison Helpline).
5. Never pull string, ribbon or tinsel hanging from the mouth (Merck) or rear end (AKC); if one end is anchored inside, pulling can perforate the gut (Merck).

Go straight to an emergency clinic if your dog is unconscious, bleeding, struggling to breathe or having a seizure (ASPCA), collapses or turns suddenly weak (FDA), or has a swollen belly with unproductive retching, an early sign of raw-dough poisoning (Merck). Before the holidays, note your nearest 24/7 emergency clinic (AVMA) and your vet's holiday hours (BVA).

Christmas Hazards for Dogs at a Glance

Timing varies between sources and between dogs. Don't wait for signs: contact your veterinarian, or your nearest emergency vet or an animal poison control center right away.

Christmas Dinner: Ham, Bones and Rich Sides

Ham and fatty scraps. Ham is salty and fatty, and too much fat can lead to pancreatitis (AKC), as can gravy, stuffing, poultry skin and meat fat (AVMA). See our ham guide.

Bones. Cooked ham and turkey bones can lodge in the esophagus, stomach or windpipe, and sharp pieces can injure the gut (FDA). Put carcasses, bones, meat string and bags in a closed outdoor bin (AVMA).

Onions and garlic. Both turn up in stuffing and gravy, cooked or not, and garlic is 3–5 times more toxic than onion. Red blood cell damage starts within a day, but anemia usually shows 3–5 days later (Merck), so call your vet or an emergency vet now rather than waiting. See our onion and garlic guides.

Drinks and dough. Dogs are lightweights with alcohol, including eggnog, vanilla extract (VCA) and rum-soaked cakes (Pet Poison Helpline). Raw yeast dough expands in the stomach and ferments into alcohol (Merck). Keep drinks (ASPCA) and rising dough out of reach; if your dog gets into either, call your vet or an emergency vet right away.

Cookies, Candy and Gifts Under the Tree

UK vet records show about 4.7 times the odds of a dog being seen for eating chocolate around Christmas (a week before to two weeks after) versus other dates, with gift boxes, Advent calendars and tree decorations among the sources (Noble et al., 2017). Dogs tearing into wrapped food gifts are a common holiday call, so keep them off the floor and ask senders to flag food parcels (Pet Poison Helpline).

• Chocolate. Cocoa powder and baking chocolate carry the most theobromine (Merck), but even white chocolate can cause vomiting or pancreatitis (VCA). If your dog ate any, call your vet or an emergency vet right away, wrapper in hand. See our chocolate guide.
• Raisin baking. Fruitcake, mince pies, Christmas pudding and panettone often contain raisins, sultanas or dried currants, and there's no established toxic dose (VCA). In a BVA survey reported in November 2025, 77.3% of UK vets surveyed had seen raisin or sultana poisoning in dogs in the past 12 months. If your dog ate even a bite, call your vet or an emergency vet right away. See our grapes and raisins guide.
• Sugar-free sweets. Candy canes, gum, baked goods and some peanut butters can contain xylitol, also labeled birch sugar or wood sugar, as can some liquid or gummy medicines (FDA). If your dog ate something sugar-free that might contain it, go to your vet or an emergency vet now (FDA). Our Halloween safety guide shows how to spot it.
• Macadamia cookies. They can cause weakness, tremors and overheating within 12 hours (Merck), and VCA adds pancreatitis; call your vet or an emergency vet. Our guide to cashews and other nuts covers them too.

The Tree, Tinsel and Ornaments

• The tree. Anchor it so it can't tip (AVMA), cover the water, which breeds bacteria (ASPCA), and add nothing to it (AVMA).
• Tinsel and ribbon. A strand can anchor under the tongue or in the stomach while the rest moves on, bunching the intestine until it saws through the wall (Merck). Skip tinsel, and collect ribbon and string as gifts are opened (FDA).
• Ornaments. Glass shards can cut the mouth and gut (VCA). Hang breakables high and skip popcorn and cranberry garlands, which can cause blockages needing surgery (AKC).
• Salt-dough ornaments. One or two can make a dog very sick (Pet Poison Helpline), even ones made years ago (VCA); signs can progress to tremors and seizures (Merck), and FDA warns the salt can be fatal. If your dog eats any, call your vet or an emergency vet now.
• Lights, cords and batteries. A chewed cord can burn the mouth and cause delayed fluid in the lungs: turn off the power before you touch your dog, then get them seen right away even if they seem fine (MSPCA-Angell, Merck). Unplug decorations when you're out (AVMA). If your dog chews or swallows a battery, don't make them vomit; get them to your vet or an emergency vet right away (Pet Poison Helpline).
• Candles and potpourri. Keep lit candles and liquid potpourri, which can severely damage the mouth, out of reach (AVMA).
• Snow globes. Some contain antifreeze (ethylene glycol), usually in low amounts (Pet Poison Helpline). It tastes sweet and can cause kidney failure 36–72 hours later (Merck); signs may seem to ease after 8–12 hours while damage continues (Pet Poison Helpline), and the antidote works best within about 8–12 hours in dogs (VCA). If your dog licked any, call your vet or an emergency vet right away.

Poisonous Christmas Plants for Dogs, Ranked

1. Yew (wreaths, garlands): can cause sudden death from heart failure; early signs are tremors, trouble breathing and seizures (ASPCA). Treat it as an emergency.
2. Mistletoe: usually vomiting and diarrhea, but it can slow the heart and lower blood pressure (ASPCA); sources range from mostly mild (Pet Poison Helpline) to potentially fatal (VCA). Call your vet or an emergency vet now.
3. Holly: stomach upset and a sore mouth. Sources differ: FDA and one Pet Poison Helpline page call it fairly mild, while ASPCA and another mention possible heart effects. Call your vet or an emergency vet.
4. Amaryllis: vomiting, drooling, diarrhea, belly pain and tremors (ASPCA); the bulb is the most toxic part (Pet Poison Helpline).
5. Lilies: true lilies cause only minor stomach upset in dogs but kidney failure in cats; lily-of-the-valley can cause a life-threatening heart rhythm in both (FDA), so call now if your dog eats any.
6. Poinsettia: overrated. The sap irritates the mouth and stomach, but serious poisoning isn't expected (ASPCA, Pet Poison Helpline), though AVMA and BVA still flag it.
7. Christmas cactus: non-toxic (ASPCA), though eating a lot can upset the stomach or cause a blockage (PetMD).

Guests, Hand Warmers and Ice Melt

• Guests' bags. Human-medication poisonings rise every November and December (Pet Poison Helpline). Ask guests to keep medicines in a closed cabinet, not a bag (ASPCA), and cigarette butts and vape cartridges, which hold nicotine, out of reach (FDA). Hand-warmer iron can cause significant stomach upset and potential organ damage, and a whole warmer can block the gut (Pet Poison Helpline); if your dog chews one, call your vet or an emergency vet right away.
• Ice melt. Many are salt-based and can cause life-threatening electrolyte imbalances (ASPCA, VCA). If your dog eats any, call your vet or an emergency vet (VCA).

Christmas Week Checklist

• Before guests arrive: Tree anchored, water covered, food gifts off the floor, medicines in a closed cabinet, ID tags current (AVMA).
• Friday, December 25: No bones or fatty scraps; carcasses in a closed outdoor bin.
• Saturday, December 26: Sweep for ribbon and wrappers, secure the trash (ASPCA), and plan an escape-proof room for New Year's Eve fireworks; if your dog panics, ask your vet about medication early (AVMA).

Frequently Asked Questions

Can dogs eat Christmas ham or a ham bone?

Better not: ham is salty and fatty and can lead to pancreatitis (AKC), and cooked bones can lodge in the esophagus, stomach or windpipe (FDA). If your dog steals a ham bone, call your vet or an emergency vet; go in right away for choking, retching or vomiting.

What Christmas dinner foods can dogs eat?

A small piece of plain, boneless turkey is fine (ASPCA), minus the skin and fat (FDA); skip anything with onion, garlic, raisins, gravy or bones. For plain sides, see our green beans and sweet potato guides or our full food list.

My dog ate tinsel. Will it pass on its own?

It might, but you can't tell at home: a strand can anchor and cut through the intestine (Merck), and signs can take hours to several days to appear (FDA). Don't pull on any you can see. Instead, contact your veterinarian, or your nearest emergency vet or an animal poison control center right away.

Are poinsettias and other Christmas plants poisonous to dogs?

Poinsettias are only mildly irritating (ASPCA, Pet Poison Helpline). Yew is the most dangerous and can cause sudden death (ASPCA); mistletoe, holly and amaryllis can also make dogs sick. Christmas cactus is non-toxic (ASPCA). True lilies mainly endanger cats, but lily-of-the-valley can cause dangerous heart rhythms in dogs (FDA).

Are Christmas trees and tree water bad for dogs?

Needles can irritate the mouth and stomach and, in large amounts, block the gut (Pet Poison Helpline). Tree water breeds bacteria (ASPCA), so cover the stand and add nothing to the water (AVMA). If your dog drank treated water or is vomiting, call your vet or an emergency vet.

Can dogs have candy canes or eggnog?

No. Sugar-free candy canes may contain xylitol (FDA), and eggnog can contain alcohol, dairy that can cause diarrhea, and nutmeg that can be toxic in large quantities (VCA). If your dog ate a sugar-free candy cane or drank spiked eggnog, contact your veterinarian, or your nearest emergency vet or an animal poison control center right away.
