We've all heard it, "Don't give your dog chocolate it will kill him". We'll how true is it you're probably wondering.The toxic dose will vary from dog to dog, depending on a number of factors such as the weight of the dog and his or her metabolism level. The problem with chocolate is that it contains a substance known as theobromine, and this substance is toxic to dogs. This substance is part of the xanthnine compound, the same family that contains caffeine and theophylline. Xanthines affect the nervous system, cardiovascular system and peripheral nerves. It also has a diuretic effect.
The good news is that it takes, on average, a fairly large amount of theobromine 100-150 mg to cause a toxic reaction. On average, Milk chocolate contains 44 mg of theobromine per oz., Semisweet chocolate contains 150mg/oz. and Baker's chocolate contains 390mg/oz. Although there are variables to consider like the individual sensitivity, animal size and chocolate concentration.
So, for example, 2 oz. of Baker's chocolate can cause great risk to an 15 lb. dog. Yet, 2 oz. of Milk chocolate usually will only cause digestive problems.
All those chocolate candy bar wrappers aren't so good for your family pet either.
