The short answer: It is not recommended.
The long answer: Chicken provides energy, builds lean muscle mass, and promotes bone health, which can all benefit your dog. However, serving your pooch uncooked chicken increases the chances of him ingesting all kinds of bacteria, such as campylobacter, salmonella, clostridium perfringens, E. coli, and yersinia. These bacteria may cause food poisoning or serious illness to your dog, resulting in gastroenteritis (blood in the vomit and/or stool) and septicemia (blood poisoning and septic fever). If your dog is pregnant, it may also cause spontaneous abortion.
Because of their underdeveloped or compromised immune systems, puppies and senior dogs are more at risk of being affected by harmful bacteria found in raw chicken. Some bacterial diseases may even be passed on to humans through contaminated water or food.
What to do if your dog accidentally eats raw chicken: Observe your dog and contact your veterinarian if you notice any changes in him. If he is infected by salmonella, he may display symptoms such as fever, shock, lethargy, diarrhea, vomiting, anorexia, weight loss, dehydration, skin disease, mucus in stool, abnormally fast heart rate, swollen lymph nodes, and abnormal vaginal discharge.
In summary: Though raw food diets are in the rage these days, consult your veterinarian before you consider serving raw chicken to your dog. It may not be advisable to feed him uncooked meat depending on his health and dietary needs.
