We’ve all heard it before time and time again, but with the increase in dog ownership worldwide in many cities, it bears repeating for first-time new pet owners and homes with children who are going trick or treating this Halloween―Chocolate is toxic to dogs and it can kill them!

Why is chocolate toxic to dogs? Chocolate contains theobromine, a compound in the same family as caffeine and theophylline (an asthma drug). In certain quantities, theobromine is toxic to dogs because a dog’s bio-physiology does not process the theobromine in chocolate like a human’s does, and therefore remains long enough in a dog’s body to cause toxicity.

Here’s an informative video clip from a veterinarian on why chocolate is toxic to dogs:

Chocolate Toxicity is Mostly about Numbers

There are basically four factors that determine whether a dog will have a toxic reaction from eating chocolate:

The size of the dog—bigger is generally better for toxicity and tolerance. However, if a large dog is older or has other health issues, what’s toxic to a much smaller dog may be toxic to a bigger dog as well.

The type of chocolate the dog ate—chocolate products have quite a bit of range in theobromine concentration. For example, dark baking chocolate contains 390 mg/oz.; Semisweet chocolate chips contain 150 mg/oz.; and, Milk chocolate contains 44 mg of theobromine per oz.

The amount of chocolate the dog ate—the less they eat the better; however, it’s not always easy to know exactly how much was eaten. Make your best honest estimation, and relay that number to your vet.

Whether the dog in question is extra sensitive to theobromine―While the first three factors are a numbers game, a pet’s sensitivity to theobromine is an unknown and so it is better to err on the side of caution in assuming that your pet is very sensitive to theobromine and seek a veterinarian to make what could be a life and death determination.
