Candy Chocolate is a tasty to pets and is toxic. It contains a compound called theobromine, which, like caffeine, is dangerous to dogs and cats when eaten in large quantities. Baking chocolate, with nearly nine times more theobromine than milk chocolate, is particularly dangerous, but either kind can be toxic to pets. There is another danger lurking within the home among the household plants, which are almost all poisonous, even if swallowed in small quantities. Peach, elderberry, and cherry trees can cause cyanide poisoning if their bark is consumed.
Insects can also be poisonous to pets such as spiders, bees, wasps, and some flies.
A few toads and frogs exude a fluid that can make a dog foam at the mouth and can even cause death. Nicotine poisoning can be caused by pets consuming the contents of full ashtrays which thoughtless smokers have left setting on low tables. Additionally, do not leave nails, staples, pins, or other sharp objects lying around. Unplug, remove or cover any electrical cords or wires near your pet. Chewing live wires could lead to severe mouth burns or death.
