While the image of a black cat feeds into many traditional Halloween decorations and tales, the painful reality is that pets are extremely susceptible to harm around Halloween. Many people fall prey to superstitions and prank them out of misplaced fear, while others simply get lost in the melee going on in the streets. It used to be so bad in certain areas that some shelters refused to allow adoption of black cats around Halloween, though most of them have stopped that superstitious behavior.
Regardless of color or size, it's best to keep your pets indoors and away from the front door at all times on Halloween night, just to be safe. Aside from pranksters, stampeding kids could unwittingly step on them, or drop candy that your pet could snatch up and eat. The sheer amount of people roaming about poses a threat in itself, as anyone could frighten your dog or cat - possibly provoking them into defending themselves. Also, an identification tag is always a great idea in case a pet manages to sneak past you through the front door.
