Who doesn’t love to eat a chocolate bar every so often? These bars taste amazing, and when you eat the chocolate, it slowly melts in your mouth. Yum! When you’re eating chocolate, your dog is probably watching and wants some of that amazing snack! But can chocolate make a dog sick?
Has your dog eaten a chocolate bar? Are you worried the chocolate bar will make your dog sick? If so, you’ve come to the right place. We understand it can be scary when your dog eats something like this.
We’ve put together some information about chocolate bars and whether they can make a dog sick. Let’s get started!
What is a Chocolate Bar?
A chocolate bar, also called a candy bar, is a candy made with chocolate. The bar may be solid chocolate or include other ingredients, such as fruit, nuts, caramel, nougat, and wafers. The chocolate bar is usually easy to break apart or bite off pieces to enjoy.
While chocolate bars are usually safe for humans (in moderation), what about dogs? Are chocolate bars safe for dogs?
Chocolate Bars & Dogs
Unfortunately, chocolate bars are toxic to dogs. The reason for this is that chocolate contains substances that are poisonous to a dog’s system. These substances are theobromine and caffeine, both of which can act as diuretics, heart stimulants, and smooth muscle relaxants.
Dogs are not able to metabolize theobromine and caffeine quickly as we can. That means these substances stay in the dog’s system, where they can cause damage to major organs.
In addition, there are several different types of chocolate, each of which contains a different amount of theobromine and caffeine. For instance, baking chocolate and cocoa powder contain the highest amounts of these substances, followed by dark chocolate, milk chocolate, and white chocolate.
In other words, baking chocolate and cocoa powder are the most toxic to dogs, followed by the other types of chocolate in order. In addition, chocolate bars that contain other ingredients toxic to dogs can also be more dangerous. This includes almonds and other nuts and more.
