(Radio Iowa) – Many Iowans are already stockpiling Halloween treats, and while they know gobbling down mounds of candy can leave kids with a tummy ache, too much sweet stuff can be dangerous, and even deadly, for pets. Jessie Phillips, director of development at the Animal Rescue League of Iowa, says chocolate is toxic to dogs and cats, and while rarely fatal, it can result in significant illness.

Phillips says it will depend on the size of the animal and how much was ingested. There’s a Pet Poison Help Hotline at 800-213-6680. Some Iowans already have a big bowl of treats on the counter, ready to go for trick-or-treat night, while kids may leave their sacks of candy laying around after they’ve had their fill. Both types of candy stashes should be hidden away from pets.

Also, Phillips says keep your pets away from carved pumpkins as those jack-o-lanterns could be full of bacteria after sitting outside.
