Don’t feed your pets Halloween candy, especially if it contains chocolate.
Make sure your pet is appropriately identified (microchip, collar and ID tag) in case they go through the open door while you’re with trick-or-treaters
Keep lit candles and jack-o-lanterns out of reach of pets
If you plan to put a costume on your pet, make sure it fits properly and is comfortable, doesn’t have any pieces that can easily be chewed off, and doesn’t interfere with your pet’s sight, hearing, breathing, opening its mouth, or moving.
If you’re pet doesn’t like strangers or has a tendency to bite, put him/her in another room during trick-or-treating hours or provide him/her with a safe hiding place.
