Keep your pets safe this holiday season by learning about common winter hazards and tips to prevent accidents and injuries.
The winter holiday season brings joy, togetherness — and a surprising number of hidden dangers for the pets who share our homes. From toxic plants and festive foods to icy sidewalks and holiday candles, the hazards add up fast. Here's a clear, category-by-category breakdown of the 12 most common holiday threats to dogs, cats and small pets, plus practical steps to keep everyone safe this season. When in doubt about your pet's health or a potential exposure, contact your veterinarian or the ASPCA Animal Poison Control Center right away [https://www.aspca.org/pet-care/animal-poison-control].
A decorated tree is irresistible to a curious pet — and it carries more risks than it looks.
Ornaments, tinsel and lights look festive — but they're magnets for pets who love to bat, chew or swallow shiny things.
The pile under the tree deserves as much supervision as the tree itself.
Several beloved holiday plants are toxic to pets. Keep all of the following completely out of reach — or choose silk alternatives:
| Plant | Risk Level | Species Most Affected |
|---|---|---|
| Lilies | Severe — can cause acute kidney failure | Cats (especially dangerous) |
| Mistletoe | Severe — cardiovascular and GI effects | Dogs and cats |
| Holly | Moderate–Severe — vomiting, diarrhea, lethargy | Dogs and cats |
| Daffodil bulbs | Moderate–Severe — vomiting, tremors | Dogs and cats |
| Poinsettia | Mild–Moderate — GI irritation | Dogs and cats |
If you suspect your pet has ingested any of these plants, contact your veterinarian or the ASPCA Animal Poison Control Center immediately [https://www.aspca.org/pet-care/animal-poison-control].
Winter walks and outdoor time carry real risks, especially for young, senior or short-coated pets.
More people, more noise and a disrupted routine can be genuinely stressful for many pets.
The holiday table is one of the most dangerous places for a curious pet. Several common foods are outright toxic.
| Food | Why It's Dangerous | Pets at Risk |
|---|---|---|
| Chocolate | Theobromine toxicity; can cause vomiting, seizures, death | Dogs, cats, small pets |
| Grapes and raisins | Can cause acute kidney failure | Dogs, cats, small pets |
| Xylitol (sugar-free treats) | Causes rapid blood sugar drop; liver failure in dogs | Dogs primarily |
| Macadamia nuts | Weakness, tremors, hyperthermia | Dogs |
| Walnuts and pistachios | GI upset; potential toxicity | Dogs |
| Cooked bones (poultry, fish, meat) | Splinter and cause airway obstruction or GI lacerations | Dogs, cats |
| Alcohol | Nervous system depression; vomiting, seizures | Dogs, cats, small pets |
A few important notes:
Holiday travel requires extra planning to keep your pet safe and comfortable.
Winter chemicals used around the home and garage can be quietly deadly.
Holiday punch, eggnog, mulled wine and cocktails should never be within reach of your pet. Alcohol depresses the nervous system and can cause vomiting, diarrhea, lethargy and, in larger amounts, seizures [https://www.aspca.org/pet-care/animal-poison-control]. Even small quantities can be harmful to a small pet. Keep drinks covered and off low surfaces during gatherings.
It's easy to let your pet's schedule slip during the holiday rush — but consistency matters more than most pet parents realize.
If you ever suspect your pet has been exposed to a toxic substance, don't wait for symptoms to appear. Contact your veterinarian or the ASPCA Animal Poison Control Center immediately [https://www.aspca.org/pet-care/animal-poison-control].
Use this quick-reference table to identify the risk level of each common winter holiday hazard and the single most important prevention step for each. If your pet ingests or is exposed to any toxic substance, contact the ASPCA Animal Poison Control Center immediately.
| Hazard | Primary Risk | Risk Level | Top Prevention Step |
|---|---|---|---|
| Chocolate | Theobromine toxicity; can cause vomiting, seizures, cardiac issues in dogs and cats | High | Never leave chocolate unattended on counters or under the tree; store in closed cabinets [https://www.aspca.org/pet-care/animal-poison-control] |
| Xylitol (sugar-free treats) | Rapid blood sugar drop and liver failure, especially in dogs | High | Read ingredient labels on all holiday baked goods and candies; keep out of reach entirely [https://www.aspca.org/pet-care/animal-poison-control] |
| Antifreeze (ethylene glycol) | Rapid, permanent kidney damage; can be fatal even in small amounts | High | Store in sealed containers in locked cabinets; wipe paws after outdoor walks; clean garage spills immediately [https://www.aspca.org/pet-care/animal-poison-control] |
| Toxic holiday plants (holly, mistletoe, lilies, poinsettias, daffodils) | Vomiting, drooling, lethargy, organ damage depending on plant and species | High | Place all live plants completely out of reach or choose pet-safe artificial alternatives [https://www.aspca.org/pet-care/animal-poison-control] |
| Macadamia nuts, walnuts, pistachios | Weakness, hyperthermia, vomiting, tremors in dogs | High | Keep all nut dishes and holiday baked goods off low surfaces and tables [https://www.aspca.org/pet-care/animal-poison-control] |
| Grapes and raisins | Acute kidney failure in dogs and cats; toxic dose is unpredictable | High | Treat as strictly off-limits; alert all guests not to share holiday snacks with pets [https://www.aspca.org/pet-care/animal-poison-control] |
| Alcohol (eggnog, punch, wine) | Central nervous system depression; vomiting, seizures, respiratory distress | High | Keep all drinks covered and out of reach; brief guests before the party starts [https://www.aspca.org/pet-care/animal-poison-control] |
| De-icing salts and rock salt | Paw irritation, GI upset if licked; some formulas toxic in larger amounts | Moderate | Switch to a pet-safe ice melt product; wipe paws and belly after every outdoor outing [https://www.aspca.org/pet-care/animal-poison-control] |
| Tinsel, ribbons and bows | Intestinal obstruction if swallowed; can require emergency surgery | Moderate | Hang tinsel on upper branches only; remove ribbons and bows from gifts immediately after opening |
| Electrical cords and lights | Burns, electric shock, electrocution from chewing | Moderate | Cover or secure all cords with cord protectors; unplug light strands when unsupervised |
| Candles and liquid potpourri | Burns from hot wax or liquid; GI irritation if dry potpourri is ingested | Moderate | Use flameless LED candles; keep all potpourri products on high shelves or in closed rooms |
| Cooked bones (turkey, poultry, fish) | Airway obstruction; bone splinters can lacerate the digestive tract | Moderate | Seal carcasses in a tied bag inside a lidded trash can your pet cannot access |
| Cold weather and frostbite | Hypothermia; frostbitten paws, ears and tail tips in young, senior or small pets | Moderate | Use booties and a warm coat outdoors; never leave pets unattended in a cold vehicle |
| Holiday tree water | Bacterial contamination; fertilizer additives can cause GI illness | Low–Moderate | Cover the water basin tightly with foil and a tree skirt; refresh water frequently |
| Stress from visitors and disrupted routine | Anxiety, hiding, escape attempts; increased risk of a pet slipping out an open door | Low–Moderate | Set up a quiet retreat room with food, water and bedding before guests arrive |
Emergency contacts to save now: ASPCA Animal Poison Control Center: (888) 426-4435 (available 24/7; a consultation fee may apply). Always call your veterinarian first if your pet shows any signs of distress. [https://www.aspca.org/pet-care/animal-poison-control]
Are poinsettias deadly to dogs and cats? Poinsettias are considered mildly to moderately toxic — they typically cause drooling, vomiting and skin irritation rather than life-threatening illness, but any ingestion warrants a call to your veterinarian or the ASPCA Animal Poison Control Center to assess the amount consumed and your pet's size. [https://www.aspca.org/pet-care/animal-poison-control]
Can a small amount of chocolate really harm my dog? Yes. Even small quantities of dark chocolate or baking chocolate can cause serious symptoms in dogs, including vomiting, rapid heart rate and seizures, because dogs metabolize theobromine far more slowly than humans do. Milk chocolate is less concentrated but still dangerous — there is no reliably "safe" amount, so treat all chocolate as off-limits. [https://www.aspca.org/pet-care/animal-poison-control]
Is peanut butter safe to give my dog during the holidays? Plain peanut butter without xylitol is generally fine as an occasional treat for dogs. Always read the label carefully — some peanut butter brands and many sugar-free products use xylitol as a sweetener, which is highly toxic to dogs even in tiny amounts. Consult your veterinarian about appropriate serving sizes for your dog's weight. [https://www.aspca.org/pet-care/animal-poison-control]
How do I know if my pet has antifreeze poisoning? Early signs can include appearing "drunk," wobbling, excessive thirst and vomiting — symptoms that may seem to improve before serious kidney damage sets in hours later. Antifreeze poisoning is a time-critical emergency. If you suspect exposure, go to a veterinary emergency clinic immediately rather than waiting for symptoms to worsen. [https://www.aspca.org/pet-care/animal-poison-control]
My cat ate a piece of tinsel — should I be worried? Yes. Linear foreign objects like tinsel, ribbon and string are especially dangerous for cats because they can bunch up in the intestines and cause a life-threatening obstruction or perforation. Do not try to pull it out. Contact your veterinarian right away, even if your cat seems fine. [https://www.aspca.org/pet-care/animal-poison-control]
What is the safest way to travel with my pet during the holidays? Book airline arrangements well in advance and confirm your carrier's current pet-in-cabin policies, as rules vary and space is limited. Make sure your pet wears an ID tag and is microchipped before you travel — the holiday season is one of the most common times for pets to go missing. If boarding, reserve a spot early and bring your pet's vaccination records.
