Hope he heals up with no lasting effects of his little binge.

My dog ate a whole Kit Kat, wrapper and all, we had to get the vet to induce vomiting. She also got into chocolate icing once, the on-call vet at A&M said baker's chocolate is worst. She was okay with a small lick of chocolate. I have heard milk chocolate is the worst, baker's is the worst, dark is the worst. So if it is chocolate I will call my vet, no use chancing it. She is so quick to grab a dropped item I hate having grapes in the house, luckily onions she walks away from.
