Levels of theobromine in Chocolate

Concentration of theobromine varies with the formulation of the chocolate

• Milk chocolate has 44mg/oz (154mg/100gm)
• Semisweet chocolate has 150 mg/oz (528mg/100gm)
• Baking chocolate 390mg/oz (1365 mg/100gm)

The theobromine in candies consisting of chocolate that is coated over some other substance - as in filled candies and chocolate coated dried fruits, etc will be more dilute than that in pure chocolate bars and solid chocolate candies.

Things like Oreos and other chocolate cookies, or chocolate ice cream, contain only a tiny bit of real chocolate. Candybars that are covered in chocolate have only slightly more. Hershey's kisses are milk chocolate, but a few aren't usually dangerous for larger dogs. Good chocolate bars and bittersweet chocolate are risky. I've been known to share my oreos and chocolate chip cookies now and then.

There is also some evidence that the effect (at least in some dogs) can be cumulative. While one incident may not be dangerous for your dog, letting them eat chocolate over time can lead to issues.

IF YOU HAVE ANY CONCERNS, CALL YOUR VET!!!! If your dog is acting strangely (very energetic, or listless, throwing up, breathing quickly, or pacing, or showing signs of pain), call immediately!
