What defines the persistent temperament characteristic carried over from the ratter phase?

Answer

Brave, determined, and highly alert disposition

Despite the breed's profound transition from a hard-working exterminator on the factory floor to a pampered companion in the drawing room, a core element of its original utility was intentionally preserved through selective breeding. The harsh conditions of mill and mine work demanded a dog that was fearless, highly tenacious in pursuit, and constantly alert to danger or movement. This inherent gameness was prioritized even above perfect looks initially. Breeders successfully maintained this terrier temperament even as the physical requirements changed to favor small size and fine coats. Therefore, the modern Yorkie possesses an outsized personality relative to its frame, requiring owners to respect this inherent bravery rather than expecting a purely docile lap pet.
