You are correct, chocolate is toxic to dogs. However, milk chocolate in small amounts isn't too bad. He should be fine. There are many other ingredients in the bar besides chocolate and he ate a small amount. Monitor for signs of pancreatitis - vomiting, diarrhea, belly pain, not eating. If you see any of these, or if you have even a small concern, have him seen by a veterinarian near you right away.

    Thank you for submitting your question regarding your dog. The risk of chocolate toxicity should be passed by now. He could still be at risk for pancreatitis, but this is less likely if the vomiting and diarrhea have stopped. I would continue to monitor him closely though and seek veterinary care if the vomiting or diarrhea recurs. Hopefully he is past the worst of it though. I hope this information helps!
