How long ago did Gracie eat the chocolate?
Based on her weight, and the amount ingested, it is likely that there may be some digestive upset, possibly causing vomiting and/or diarrhea.
Life-threatening effects would not be expected based on 65g of milk chocolate in a 6kg dog.
Gracie ate the chocolate about half an hour ago and appears well and breathing normal
