Halloween can be a dangerous holiday for pets because it stacks multiple hazards on top of each other at the same time: the candy bowl, the open front door, the noise, the costumes, the candles, the guests. Any one of those is manageable. All of them at once, on a night when nobody is paying full attention, is when things go wrong.
Here’s what we see come through our doors on and around Halloween, and what to do if it happens to you.
Candy and Food Toxicity
This is the big one. Halloween brings concentrated quantities of the most common pet toxins directly into your home, at floor level, in crinkly packaging that makes them even more appealing to a dog.
Chocolate
Theobromine in chocolate is toxic to dogs, and the danger scales with both the type of chocolate and the size of the dog. Dark chocolate and baking chocolate are the most dangerous. Milk chocolate is less concentrated but not safe in quantity. White chocolate contains almost no theobromine but is high in fat and can cause pancreatitis.
Signs of chocolate toxicity include vomiting, diarrhea, restlessness, excessive urination, rapid breathing, muscle tremors, and in serious cases, seizures. Symptoms can take 6 to 12 hours to appear, which means a dog who raided the candy bowl at 7pm may not show signs until the middle of the night.
If your dog ate chocolate, call us or ASPCA Animal Poison Control (888-426-4435) right away. The amount matters, the type matters, and the size of your dog matters. Do not wait for symptoms.
Xylitol
Found in sugar-free gum, sugar-free candy, some peanut butters, and other products that may be sitting on a table or in a bag, xylitol causes a rapid and severe drop in blood sugar in dogs and can lead to acute liver failure. Symptoms can appear within 15 to 30 minutes of ingestion. This is an emergency. Do not wait to see how your dog feels.
Candy wrappers and packaging
Wrappers are not food, but dogs eat them anyway. Foil, plastic, and cellophane wrappers can cause GI irritation, obstruction, or choking. A dog who has eaten a significant amount of packaging material alongside candy may need to be evaluated for obstruction risk.
Raisins
Sometimes found in Halloween treat mixes or given as an alternative treat. Any amount of raisins or grapes in a dog warrants a call to a veterinarian. The mechanism of toxicity is still not fully understood, which is part of why there is no established safe dose.
Escaped and Lost Pets
Halloween is a common night for pets to go missing. The front door opens dozens of times over the course of trick-or-treating hours, and a dog who would never normally bolt may take advantage of the chaos. Fireworks and loud noises common in some neighborhoods add an additional flight trigger.
The best prevention is keeping dogs and cats in a secure back room with the door closed during peak trick-or-treat hours. If your pet does get out, make sure their ID tags and microchip information are current before Halloween arrives.
A scared pet who has been loose, especially in traffic, may come home with injuries that are not immediately obvious. Check them over carefully when they return, and come in if anything seems off.
Candles and Burns
Jack-o-lanterns and decorative candles are a fire and burn risk for curious pets. A cat who investigates a lit candle too closely, or a dog who swipes a tail through a flame, can sustain burns that range from minor to serious. Battery-operated candles are a simple and worthwhile swap.
Glow Sticks and Decorations
Glow sticks are non-toxic but the liquid inside tastes intensely bitter and causes profuse drooling and pawing at the mouth when a pet bites into one. It looks alarming but typically resolves on its own with a water rinse. If you see this, offer fresh water, wipe out the mouth if possible, and monitor.
Small decorations, fake cobwebs, rubber spiders, and other prop items can be chewed and ingested, particularly by puppies. GI obstruction risk applies to any non-food item consumed in quantity.
Costumes
From an urgent care standpoint: costumes that restrict breathing, limit vision, cause significant distress, or have small parts that can be chewed off and swallowed are the ones we occasionally see come through the door. If a costume is causing a pet to pant heavily, freeze up, or is wrapped around the neck or chest, take it off.
When to Come In
Take your pet to the vet if:
- Your dog ate chocolate and you are unsure how much or what kind
- Your dog ingested anything containing xylitol
- Your pet ate raisins or grapes
- Your pet is vomiting, trembling, having seizures, or seems weak or disoriented after any candy exposure
- Your pet sustained a burn from a candle
- Your pet was loose in traffic and may have been hit or injured
- Your pet has a bite wound from another animal encountered while outside
