Keeping your pet home in a secure area is best, perhaps a basement or room where the pet will not be exposed to the various "spooks and goblins" ringing the doorbell, causing them undue anxiety and stress. This avoids a pet escaping to be lost or injured and prevents the chance of someone being bitten by a frightened animal.
Lastly, a word about pets getting into the "booty." Remember that animals can get very ill eating candy, especially chocolate. So have fun and protect your pets this Halloween.
