Dog ate some chocolate wrapped in tin foil... Will he be okay?

This is more myth than anything factual. I spoke with several veterinarians about dogs consuming chocolate. All of them said that chocolate was NOT poisonous for a dog. It's the SUGAR in the chocolate that's bad for them. Having said that, too much of anything can make a dog sick enough to throw up. If he's eaten the foil, this too, shall p. (pun intended.) I think your dog will be fine.
