Halloween is a time for thrills and scares that get the adrenaline pumping. However, there isn’t a scare quite as real or terrifying as seeing your four-legged family member getting into something they shouldn’t. Who can blame them? With unusual decorations, pumpkins, apples, chocolates and candies everywhere, their already-heightened senses are even more stimulated.
As pet parents, it’s crucial to stay vigilant and prepared for any situation. In this blog, we’ll cover the most significant threats around your home, how to recognize signs of toxicity and what to do if your dog is exposed to something harmful. Keep in mind, if your pet ingests anything on the list below, we recommend seeking veterinary care right away. In many cases, inducing vomiting or starting treatment immediately will minimize serious complications.
Halloween Candy and Chocolate Toxicity for Dogs
Xylitol in Sugar-Free Candy and Gum
Many sugar-free chewing gums and candies contain xylitol, a sweetener that is extremely toxic to dogs but not humans. Xylitol is over 100 times more toxic to dogs than chocolate. Ingesting even a small amount can cause their pancreas to rapidly dump insulin into their bodies, which can lead to hypoglycemia (low blood sugar). Symptoms of xylitol poisoning include vomiting, weakness, lethargy, seizures and, in extreme cases, liver failure. That’s why it’s crucial you get your pet to an emergency vet hospital as soon as possible if you know or suspect they ate something that contains xylitol.

Caffeine and Theobromine in Chocolate
Chocolate is notoriously dangerous to dogs. While rarely fatal, consuming chocolate of any kind can make them sick because of two specific compounds: caffeine and theobromine. Dogs’ bodies metabolize these compounds slower than humans, so it can stay in their system for longer.
It’s important to note that all chocolate is harmful to dogs in any amount; however, dark chocolate contains higher levels of these toxins, making it more dangerous than other kinds like milk and white chocolate. Even a small amount of dark chocolate can cause severe symptoms like cardiac arrhythmias and seizures, which can be life-threatening if not treated immediately.
Candy, Wrappers and Packaging Hazards
While many Halloween candies and chocolates contain high levels of fat and sugar causing vomiting, diarrhea and abdominal pain, their wrappers can be just as dangerous. Dogs may swallow foil, plastic, cardboard or paper packaging that still tastes like its contents, which can lead to intestinal blockages or choking. Signs of gastric obstructions include vomiting, lack of appetite and difficulty passing stool.
Signs Your Dog May Have Ingested Something Toxic
If your pup has ingested something harmful, it could lead to vomiting, diarrhea, excessive drooling, lethargy and weakness. In more severe cases, you may notice rapid breathing, seizures or a lack of coordination.
If you notice any or all of these symptoms, do not wait—visit your emergency vet right away. Quick action is crucial as symptoms can worsen rapidly. Early treatment can make all the difference.
Dangerous Halloween Decorations and Costumes for Dogs
Halloween decorations like the ones listed can be harmful if ingested by your canine companion:
- Glow sticks – Glow sticks contain a liquid that can irritate your dog’s mouth and stomach.
- Fake cobwebs – Decorative cobwebs can cause your dog to choke and cause intestinal blockage if swallowed.
- Pumpkin spice – Many pumpkin spice-flavored or scented items contain essential oils that are toxic to dogs, such as nutmeg and cinnamon oils.
- Fake blood, slime and goo – May contain chemicals that can be harmful when ingested.
In addition, small decorations or costume parts, like beads, buttons or things that may look like dog toys can pose as choking hazards. If your dog is coughing, gagging or has difficulty breathing, they may have swallowed a small object. Call an emergency veterinarian immediately in these situations.
What to Do If Your Dog Ingests Something Toxic
If you suspect your dog has ingested something toxic, remain calm. Remove the item if it’s still accessible. If your dog is showing signs of distress and discomfort, please visit our emergency vet in Apex right away. Avoid attempting to induce vomiting unless instructed by a professional, as this can cause more harm than good.
To avoid these situations, be proactive in keeping harmful items well out of your dog’s reach. Store candy and other treats in high places and enclosed containers, use pet-safe decorations and monitor your dog closely during Halloween festivities, especially if you’re hosting or have trick-or-treaters around.
Dog-Safe Halloween Treat Alternatives

If you want to give your pup a special Halloween treat, there are many recipes on the internet for pumpkin-based treats, dog biscuits or even a bit of unsweetened peanut butter. These alternatives keep your pet happy and healthy while still feeling included in the Halloween fun. That said, be sure to also monitor their treat intake and overall behavior to avoid overfeeding them.
