Ok so I need some help please! I left a small piece of chocolate bundt cake on the table while I took a shower and when I got out he had just finished eating it! I don't know what to do! He is extremely hyper and won't calm down! I'm scared to death because I have heard that chocolate will kill a dog and I don't know actually how much chocolate is in it to know if it will hurt him or not! Will someone please help me! I can't lose my Charlie!
