Why You Should Never Feed Chocolate To Your Dogs

Come on! Who doesn’t like chocolate? Most people I know will sneak a piece of chocolate at least once in a while.

Just the word “chocolate” is enough to make your mouth water. In fact, if I were to say the word ‘chocolate’ enough times, some of you would probably rush to the fridge and devour the last piece of chocolate you’d been saving for an ‘opportune’ moment.

For the time being, let’s keep our own interests on the back-burner and see how this habit of ‘chocolate-devouring’ affects the other creatures with whom we share our planet.

Hey Puppy! Do You Want Some Chocolate?

Regardless of how deliciously pleasant chocolate may be to our senses (predominantly smell and taste), chocolates are not great for animals, especially for dogs. There have been many incidents around the world when feeding chocolate to a pet like a dog or a cat resulted in unexplained illnesses, or in some cases, even death!

For dogs, it’s pretty much like this:

Oh Chocolate! Why is Thee Bad for Me?

Let’s look at what chocolate actually contains. Firstly, a chocolate contains theobromine, which is an alkaloid chemical like caffeine (you must have heard of ‘caffeine’ being associated with coffee, various drugs, and so on). It seems good when consumed, but in reality, it isn’t that great for your body if consumed in large amounts. Even in human beings, caffeine can cause diarrhea, vomiting, and if taken in high quantities, it can even lead to heart failure or seizures.

Essentially, the consumption of chocolate is bad for both humans and dogs alike, but there is a catch…


Not as Good as Humans… No Offense!

If chocolate isn’t good for humans either, why can a man get away with consuming this amount of caffeine, but a dog will fall ill?

Human’s ability to consume this level of caffeine is due to difference in the respective bodies of dogs and humans. You see, the metabolism of dogs has not evolved as elegantly as that of humans; therefore, the enzymes that take care of these plant chemicals are still not ready to deal with them efficiently.

Dogs are about 3 times more sensitive to chocolate than humans, per kilo of body weight, so two 120-gram (4.2-ounce) bars of dark chocolate are enough to make a 20-kilogram (44-pound) dog ill, while half a kilogram (1.1 pounds) could even be fatal to the poor canine.

While this quantity looks wonderful for chocolate lovers around the world, dogs have a hard time dealing with the chemicals that chocolates have hidden within
