Halloween’s all fun and games… until your dog eats a candy bar or your cat bolts at the sound of the doorbell.

Good news, just a couple small adjustments and you can keep things festive and safe! Think of it as helping your pet enjoy the holiday their way: calm, cozy, and free of spooky surprises. Here are our best practical tips, plus advice straight from our Licensed Veterinary Technicians, to make sure everyone has a happy Halloween, paws and people alike.

1. Halloween Candy and Pets

Halloween means candy bowls, wrappers, and temptations everywhere, and pets have noses like radar. But many “treats” are dangerous:

  • Chocolate contains theobromine and caffeine, both toxic to dogs (and cats) with symptoms ranging from vomiting to heart failure.
  • Xylitol (a sugar substitute in sugar-free gum or candy) can cause sudden, life-threatening drops in blood sugar and liver damage in pets.
  • Raisins, grapes, and some nuts can cause serious kidney or digestive issues.
  • Candy wrappers and packaging can choke or block intestines.

Tips from the Vet Techs:

  • Keep candy in sealed containers, high cabinets, or closed drawers.  – Val, LVT
  • After trick-or-treating, make sure children and guests don’t leave candy within paws’ reach. – Corrine, LVT
  • If a pet does get into candy, call an open vet clinic or the ASPCA Animal Poison Control Center (1-888-426-4435) right away.

2. Create a “Safe Zone” for Pets on Trick-or-Treat Night

Between doorbells, strangers in costumes, flashing lights, and loud noises, Halloween can feel like sensory overload for pets.

  • Keep pets indoors during trick-or-treat hours, it lowers the risk of stress or escapes. 
  • Give them a quiet, cozy room away from the front door, with their favorite bed, toys, and a soft blanket. The radio or a while noise machine can help muffle doorbell sounds.
  • Close blinds or block views of trick-or-treaters if your pet is visually reactive. 

Tips from the Vet Techs:

  • The front door opens a dozen (or hundred) times, prime time for a dog to dash out.  Even the most calm pets might feel like bolting in the chaos.  Practice “wait” or “stay” training early, or avoid door access altogether.  “You, too, can prevent door-dashing dogs!” – Corrine, LVT

3. Costumes… Only If They Comfortably Fit

We all love adorable pet costumes. But for many pets, costumes are stressful, especially if they restrict movement, hearing, or vision.

Things to watch for:

  • Dangling parts or chewable details that become choking hazards. 
  • Ill-fitting designs that can twist or catch on something. 
  • Anything that covers ears, eyes, muzzle, or limits natural movement.

Tips from the Vet Techs:

  • Don’t forget your costume, cats are extra curious about shiny things.  People costumes with tulle, glitter, tinsel, or stringy details can be risky if left out. – Miya, LVT
  • Let your pet try the costume on a few days early, if they freeze or resist, skip it. 
  • Supervise pets in costume. Never leave them unattended.  If in doubt, go simple, a themed bandana or collar can be just as festive.

4. Walk & Visibility Safety on Halloween

Even confident pets can get startled on Halloween night. Busy sidewalks, flashing decorations, and costumes can throw off their sense of safety.

Do this:

  • Take your pet for their walk earlier in the day, before the roads and sidewalks fill up with trick-or-treaters.
  • Choose quieter routes and use a non-retractable leash to keep them close and secure.
  • Make sure your pet wears up-to-date ID tags and has a microchip with your current contact info.
  • Use reflective collars, leashes, or vests for any after-dark outings, they help drivers and pedestrians see you both.

Tips from the Vet Techs:

  • If your pet joins you for trick-or-treating, monitor their body language and stress level closely.  There’s a lot going on, what’s the dog eating off the ground, what did my kiddo just eat, will my dog like that dog, can I see my kiddo on the porch?!  Keeping your pet and little trick-or-treaters safe is a big job on Halloween. If your pet’s overwhelmed, it’s okay to skip the outing so they can be home safe, or head home early. – Shelly, LVT

5. Avoid Decoration Dangers for Pets

Decorations are festive, and many can be pet hazards in disguise.

Hazards include:

  • Lit candles and jack-o-lanterns: pets can knock them over, leading to burns or fires. 
  • Wires, cords, and string lights: chewing on these can cause electrocution or burns.
  • Glow sticks, batteries, and small plastic pieces: if broken or ingested, these can irritate or even poison.

Tips from the Vet Techs:

  • Place candles inside protective containers or skip open flames entirely in pet-accessible areas.
  • Monitor pets around decorations, curiosity piques with new smells and décor at their level.
  • Fake cobwebs can big a big danger for curious cats, they love to get into and chew on new stringy things and it can cause intestinal blockages.  If you’re decorating with cobwebs, do your best to keep them out of curious cat reach. – Miya, LVT

6. Be Ready & Know Your Halloween Emergency Plan

Despite our best efforts, accidents can happen. Preparation is key.

  • Save Ralston Vet’s number (402-331-6322), a 24-hour animal emergency clinic, and ASPCA Poison Control (1-888-426-4435) in your phone. (ASPCA)
  • Know the signs of distress or poisoning (vomiting, seizures, drooling, lethargy).
  • Don’t hesitate to ask, early intervention is often lifesaving.
