A gun dog is a type of canine that is specifically trained to assist hunters in finding, flushing out and retrieving game birds or other wildlife. These dogs are often used for hunting activities such as upland bird hunting, waterfowl hunting, and even big-game hunting. Some common breeds of gun dogs include the Labrador Retriever, Golden Retriever, English Setter, German Shorthaired Pointer, and the Brittany Spaniel among others. These dogs are highly valued for their keen sense of smell, strong retrieving instincts, and good temperament in the field.
