There are few food items more beloved by humans than chocolate. As of 2014, the global chocolate industry was worth $80 billion, with demand expected to rise 30-percent by 2020.
It’s the taste of chocolate that draws humans to it. And most animals love the taste, too, but that’s where things get dangerous for our furry friends. The problem lies in the cocoa beans in chocolate. They contain a substance called theobromine, a chemical that’s often toxic to small animals, like dogs. The good news is that cocoa content is lower in milk chocolate, which is more popular than dark chocolate.
