What are some of the traits that have been exaggerated through selective breeding in dogs?

Selective breeding in dogs has exaggerated traits such as size, coat type, and temperament. For example, breeds like the Great Dane have been bred for their large size, while toy breeds like the Chihuahua have been minimized to very small proportions. Additionally, certain breeds have been selected for specific coat characteristics, leading to extreme variations in fur length and texture. Temperament traits, such as aggression or docility, have also been amplified to meet human preferences for specific roles, like guarding or companionship.
