Halloween (tomorrow night) may be fun for children, but it can be traumatic for dogs. Door bells ringing, doors opening, and lots of commotion around the neighborhood can upset a dog's routine. Candy, particularly chocolate, can be toxic to dogs. And while it may seem like a good idea to take your dog trick-or-treating with the kids, the Humane Society of the United States advises you to leave your dog at home. The street noise and unfamiliar people could cause your dog to "act out of character."
