Making breaded chicken from scratch allows you to control what ingredients go into the crunchy coating making it a tad bit better for your dog to take a small bite without any cause for alarm.  However, the frying process will still not be good for your dog as the grease from the fried chicken could cause problems like GI distress or pancreatitis. You can let your dog nibble on a tiny bite but you should expect symptoms like vomiting and diarrhea which is fine. If the symptoms persist, call your vet for further instructions while monitoring any behavior change.
