Pets have become an indispensable part of Halloween for many families.

Americans are expected to spend $330 million this year to dress up their furry companions as hot dogs, pumpkins, monsters and other colorful characters.

Many people also bring their pets along as they trick-or-treat.

But Halloween poses some unique safety risks for Fido and Mittens.

Dogs may love everything chewy, but candy is for people -- not pets, said the Montgomery County Animal Resource Center in Ohio.

Chocolate is dangerous for dogs and cats, and consuming too much of it can prove deadly, the center said.

Holiday decorations such as pumpkins and corn are relatively non-toxic to cats and dogs, but they can produce upset stomachs.

However, other decorations such as electric lights and pumpkins with candles inside, should be kept in places where pets cannot reach them.

Pets can suffer burns of electrocution by chewing on cords. Candles pose fire risks.

Pet costumes should not restrict the animals' movements or impact their ability to see, hear, breathe, bark or meow, the center said.

Owners should inspect costumes prior to putting them on to make sure there are not dangling parts or fabric that could be a choking hazard.

Pets should have the proper identification tags in case they get loose.

Owners should be careful when opening doors for trick-or-treaters to make sure their furry friends do not escape.
