Chocolate is especially toxic to some pets. Suckers and taffy apples are dangerous because a swallowed stick could obstruct or perforate the pet's stomach or bowels. If you dress your pet in a costume, be careful to remove all rubber bands afterward. Rubber bands mistakenly left on can quickly burrow into an animal's skin. Be careful with holiday decorations.
Pets can chew or swallow crepe paper, fake cobwebs, plastic spiders and cardboard wall hangings.
