In many cases this scenario represents a typical hunting season day in a pointing labs life. In reality, it is not very important. Most puppies are chosen at 6 to 8 weeks of age. This is too young to be able to predict what this dog will ultimately become. Appearance is the number one selection factor and features will change, the smallest pup can turn out to be the largest, etc.
Personalities change the moment they leave the litter.
Dr. Battaglia defines other as environment, nutrition, training, and socialization. The color of a pointing lab makes no difference in ability. Due to supply and demand the color can make a difference in price. The gender gap in labs regarding trainability is very small. The important factor is their position in the pecking order of the litter.
