Q. What could happen if my dog ate leftover grilled chicken cutlets that were in my garbage?
A. If they were spoiled, he could certainly be susceptible to food poisoning. If they were just discarded, the rich meal could cause some intestinal upset, vomiting, diarrhea. By cutlets, I take you to mean they were boneless, that's good. Even if he ate some bones, the best thing to do is wait it out, feed him some extra dry food to help pad them as they pass through and watch his bowel movements for signs of blood or diarrhea. If he does start vomiting, gets diarrhea, loses his appetite, becomes lethargic, get him in to the vet as soon as possible.
