Important Note: While genetics play a significant role in determining a dog's physical features, it is important to remember that the environment also plays a role in shaping their development. For example, a dog's diet and exercise can impact its size and muscle mass.
It's also worth mentioning that many breeds have been selectively bred over generations to enhance specific physical features. This means that some traits are more likely to be passed down within a breed than others.
