Everybody likes to eat chocolate that is delicious and uplifts one's mood because it contains phenylethlyamine (also known as the love drug), which causes excitement, quickens the pulse rate, and makes you happy but it can be extremely dangerous for your pet dogs.
Both chocolate and cocoa contain theobromine that the human body can easily digest but dogs can’t. Even a small amount of chocolate can make their stomach upset. In large quantities, it can cause internal bleeding, tremors or even cause a heart attack. Chocolates also contain sugar or sweeteners. The main ingredient is xylitol, which is equally dangerous. It leads to vomiting, stomach bloating, seizures and liver failure.
With dogs, it’s a matter of having too much, which then causes neurological problems, including seizures and death. This may be because it built up in their system when a person lets them have small amounts on a regular basis (they don’t process it as fast as humans), or because they got into a large amount of chocolate and gorged themselves just once.
