Where's my chocolate?

I had this awesome chocolate bar I got from the co-op the other day. It was like $4, the kind you eat a tiny bit of each day over the course of the whole week. I accidentally left it next to the computer the other night when I was shutting it down so I could go to bed. The next morning I was looking for it so I could put it away but I couldn't find it.

Over the course of this week I've been searching everywhere, as well as asking Zach if he's seen it. Today I finally said to him that I couldn't find it and where could it possibly be? He told me one of the dogs probably ate it. I said no way, that they would be dead, or at the very least there would have been some trace of it, a bit of wrapper, or chocolate smudge somewhere. Zach then informed me that Mango had puked in the middle of the night and he had cleaned it up on Tuesday morning. He said it was brown and had foil in it.

There's my chocolate. This was had 85% cocoa content because why have chocolate if you're not going to have CHOCOLATE?

Mango's been acting berserk all week, eating papers mostly every time I leeave the house, even just the room sometimes. Anyway, isn't that much chocolate supposed to be really bad for dogs? How come Mango is still alive? She's indestructible.
