Okay, here's the deal. No matter how good it smells... never eat chocolate. Take my word for it, it's just no good for you. However... our two-legged persons love the stuff and, by and large, it doesn't seem to hurt them at all.
I know, I know, you show your love to them with wagging tails, woofs, kisses, and so on. But, trust me, they're really going to love free chocolate!
The Mars company has a shameless advertising promotion going called the Mars Real Chocolate Relief Act. Every single Friday in September they're giving away free chocolate. So, fetch this link for your person.
If your person is a chocolaholic like my mama... who knows, they might be so delighted there'll be an extra dog bone for you!
