Chocolate toxicity depends upon the dose of chocolate ingested--this is related to size of the dog and amount eaten. If the donut was chocolate covered I would not be too concerned. Milk chocolate is less toxic than baking chocolate or cocoa. Even the amount of chocolate in a 100% chocolate donut would probably not be enough to cause concern. Initially signs of toxicity due to chocolate are vomiting and lethargy. If these progress and your dog becomes very lethargic or starts tremoring have him seen immediately by a veterinarian.
Any dog that eats food he's not accustomed to can cause gastrointestinal side effects--like vomiting and especially diarrhea. The diarrhea often starts 1-2 days after ingestion.
You can give your dog Pepcid at a dose of 0.5 milligram per kilogram body weight by mouth twice daily to help settle the stomach and try to prevent vomiting. A bland diet can help too--boiled chicken, boiled rice, canned pumpkin, and plain yogurt.
Vomiting can be induced within 2 hours of ingestion of things like donuts. Do NOT use ipecac--this is not safe in dogs. The at home emetic of choice is hydrogen peroxide. Use 1 teaspoon per 5 pounds of body weight and do not exceed 3 Tablespoons per dog. This can be repeated once if vomiting has not occurred in 10-15 minutes. After 2 hours most of the ingesta has left the stomach and making your dog vomit will do nothing.
You can always call your veterinarian for their assessment of the amount of chocolate eaten. They know your dog, his size etc and will be able to give you the best idea if this will be a problem.
