Known for trick-or-treaters and candy, Halloween is around the corner, but a certified K-9 behavior health specialist has a warning for those with animals at home.

Usually, after a candy haul from the neighbors, kids spread out their goodies on the floor to pick out their favorites. However, Dr. Valeri Farmer-Dougan says many animals, like dogs, take advantage of the opportunity to eat the candy. Reports indicate that many sweet treats are toxic to animals.

According to the American Veterinary Medical Association, some candies, like raisins, can cause pet kidney failure. According to Dr. Farmer-Dougan, pet owners can call the Animal Poison Control hotline if a local hospital is not open on Halloween.

That hotline is 888-426-4435.
