The Border Terrier is one of the oldest and smallest of the working terrier breeds that originated in Great Britain. Earlier names for this breed include the Reedwater Terrier, Ullswater Terrier and Coquetdale Terrier. They are well-known for their scruffy face and beard and their friendly, welcoming disposition. They are active, agile and sturdy little dogs, said to be “hard as nails” and “as game as they come.” This breed thrives on human companionship and does well around children. However, they should not be in homes with other small animals such as birds, hamsters or mice, and they always will be inclined to chase cats. Border Terriers are friendly to everyone, including strangers, but will sound an alarm when something new or unfamiliar appears in their home territory.
