The neighborhood is teeming with ghosts, goblins, witches and princesses. A big bowl of candy is ready by the front door. Children are excited and ready to go trick-or-treating.

While the children, and parents for that matter, are excited for the yearly tradition of going door to door to collect candy, other members of your household may not be quite as thrilled.

Halloween, though fun for children and adults, can be frightening and even hazardous for your pets, said Dr. Elisabeth Giedt, director of Continuing Education, Extension and Community Engagement at the Center for Veterinary Health Sciences at Oklahoma State University.

"Your pets can become alarmed with all of the extra activity in your home, your doorbell ringing often, and the strange costumes," Giedt said. "A lot of dogs feel they are the guardians or protectors of their home. They may feel threatened when a stranger enters their area and could bite or scratch someone. Pet owners need to make preparations for their animals before Halloween to help keep them from getting scared and confused once all of the activity begins."

Pet owners may consider placing their animals in a safe area. This may be in a crate with a favorite toy or treat, or in a room in the house that is not near all the activity.

Pet owners also need to be aware of the dangers of animals accidentally ingesting Halloween treats, especially chocolate varieties.

Giedt said the cocoa in chocolate can be poisonous for cats and dogs. The darker the chocolate, the more deadly it can be. In addition, Xylitol, an artificial sweetener used in many types of chewing gum and baked goods, has been shown to be poisonous to dogs.

It is not just the candy itself that can pose a danger to your pets.

"Some pets will consume a piece of candy whole, including the wrapper. This can potentially cause an intestinal blockage," she said. "If you believe your pet has consumed candy or any other potentially dangerous foods, contact your veterinarian immediately. A quick response could save your pet's life."

If you have decorations in your home, such as balloons, pumpkins or candles, make sure they are not accessible to your pets. An excited animal could knock over a candle and start a fire or suffer burns.

With the front door opening and closing many times throughout the evening, your animals must have proper identification in case they get out of the house. A tag with your name and phone number, or microchip identification, will make it more likely for you to be reunited with your pet.

"Halloween can be a lot of fun for children and adults, but nothing can ruin the fun faster than an emergency trip to the hospital, or to the veterinarian because your pet got into the candy bowl or became scared enough to scratch or bite a trick-or-treater," Giedt said. "Keeping your pet safe during the holiday will help ensure everyone has a fun and memorable evening."
