Terrier breeds come in a variety of size, some being small and some quite large, and were originally bred to hunt vermin, like rats or even badgers and foxes. These breeds aren't anxious or timid, as they were bred to be tough and determined. The word Terrier even comes from the Latin "terra" and is the modern French for "burrow". Terriers will keep your garden and home pest free as well not being afraid to meet new people.
