Dog size does not always predict behaviour, and personality often defies expectations.
Some large dogs are calm, affectionate, and happiest staying close to their people, while certain small breeds carry themselves with remarkable confidence and determination.
These differences usually reflect a mix of genetics, historical purpose, and individual temperament rather than physical stature alone.
A dog bred for companionship may crave closeness regardless of size, while a smaller breed developed for alertness or independence may display outsized confidence.
Understanding these contrasts can help potential owners choose a dog whose personality fits their lifestyle, rather than relying on size-based assumptions.
