I know there's another Border Terrier thread. But it didn't really talk about the breed. So here's some info that I found on google

The Border Terrier shares its ancestry with that of the Bedlington Terrier and the Dandie Dinmont Terrier and is one of several working terrier breeds to come from the borders of England and Scotland. The breed was developed by farmers and shepherds who used the Terriers to hunt fox, otter and vermin for centuries. The Border's most important characteristics are still those necessary for the performance of his work. His job is to follow his quarry and "go to ground". He must either go underground to chase out the fox ("bolt") or remain with the fox and bark. By barking, the dog is indicating where the fox is located.
The Border Terrier was officially recognized by the Kennel Club (U.K.) in 1920 but history shows that the breed was in existence in the 19th century. In the last few years, the Border has become one of the most popular Terrier breeds registered with the Kennel Club. According to the Border Terrier Club (U.K.), as of 2003, the Border Terrier was listed as the 10th most popular breed in the United Kingdom.
The Border Terrier is good-tempered, affectionate, obedient and easily trained. He is noted for being active and agile. His body posture is "at the alert" and he is determined and fearless. Being a high energy breed, the Border Terrier needs plenty of exercise and enjoys such activities as flyball, agility, tracking, earthdog tests and obedience competitions.
Borders generally get along well with other dogs as well as cats if introduced at a young age. Caution is advised, however, around other small animals such as gerbils, guinea pigs, hamsters, rabbits, birds and neighbourhood cats, as they may be viewed as vermin because of the Borders strong hunting instinct.
In colour the Border Terrier may be red, grizzle and tan, blue and tan, or wheaten. All colours usually have a ring of coarse silver based hair about a third of the way from the base of the tail. Most Borders have dark ears and muzzles.
Is there any Border Terrier owners out there? I'd like to hear more about them
