Here's why:
* Individual Variation: Just like humans, dogs have different builds, muscle mass, and athletic abilities. Some labs are naturally faster than others, regardless of color.
* Training and Exercise: A lab's speed depends on how much it's trained and exercised. A well-trained and physically fit lab, regardless of color, will be faster than a sedentary one.
* Coat Color: A dog's coat color doesn't influence its speed.
In summary, the speed of a Labrador Retriever is determined by individual factors, training, and exercise, not its coat color.
