What is the difference between a terrier dog and a regular dog Terrier dogs are not a breed, they are a large classification under which different breeds of dogs are included, and all of these dogs included are of the terrier breed. Terriers are a class of dogs that were first used to hunt and eliminate poisonous snakes, vermin, and voles. Terriers are energetic and active, and they are very loyal and affectionate to their owners. They were used to control and eliminate mice, rabbits, and foxes above and below ground. Terriers are usually small, sensitive, very expressive and excitable. The best feature is a very strong, muscular loin with a very slight upward arch. The tail is positioned slightly higher and can be held happily, but not curled. You look closely at all breeds of terrier dogs and they all exhibit these characteristics. The birthplace of the terrier dog should also be little known, most of the breeds of terriers were bred in the British Isles.
