You should call pet poison helpline @ 855-764-7661 to go over the exact quantity (gm's) of candy Curry ingested and determine if that was a toxic dosage or not. As an alternative you can also enter in the specifics into the online chocolate toxicity calculator http://veterinaryclinic.com/chocolate/calc.html I would guess that the amount he ingested (approx. 26.25 gms) was too small to be of toxicity concerns, but I would encourage you to double check with the actual dosages since you have the information from the bag of candy there in front of you.

    An entire bag of fun-sized M&Ms weighs 21 grams, and as we know that's not all chocolate. I can't find a good reference as to how much chocolate is in that quantity of M&M's, but according to my chocolate toxicity calculator even if it were all chocolate it likely still wouldn't be enough to make Curry sick. A mini Baby Ruth has even less chocolate, and is mostly peanuts. I would monitor him closely for the next 24 hours for vomiting, diarrhea, tremors, or seizures, but I suspect he will be just fine. If you want to be absolutely certain, you can take him in for emergency treatment, and they can induce vomiting and give activated charcoal to absorb any residual theobromine in the gut.

    Oh dear! There isn't a very high cocoa content in either of these candies - but since Curry is such a small dog, I would still be concerned that this may cause problems. The safest bet would be to take him to your nearest emergency vet - if he ate the candy within the past few hours, they can give him an injection to induce vomiting and hopefully get most of the chocolate out. If needed, the vet may also administer activated charcoal and start supportive care to help minimize the risk of any serious issues.
