Terrier Dog Temperament
The very nature of the tasks traditionally required of a Terrier dog needed an energetic, tenacious, brave and exceedingly determined dog.
The very nature of small vermin control tends to result in a fairly small legged but very robust build suitable for entering the lair or burrow of it's intended prey.
Terrier dogs have in the past always been viewed as real assets by their owners and have worked with man for centuries in their assigned roles.
Today most Terrier dogs are kept primarily as pets but they still retain the bred in traits traditionally required of a vermin hunting dog, they all tend to still posses their energetic, tenacious, brave and determined temperament.
