Chocolate risks

Question
My 7 month old male Pom just ate 3/4 of a chocolate cookie.  He weighs about 11 lbs.  I just had him to the vet yesterday for vomiting, lethargy, etc., and he is back to his active self today, thankfully.  What can I expect from this latest episode?  Should I call the vet?

Answer
No need to fret. There is very little real chocolate in a cookie, and even less in 3/4 of a cookie. The only problem might be a little gi upset. If he was already suffering from a gi issue this may delay his recovery a day or so. I would not be too concerned.
