Explanation

A terrier is a type of dog. Terriers are usually brave, strong, small dogs with wiry coats. In The Wizard of Oz, Dorothy's dog Toto is a terrier. Most terriers have short, muscular bodies. There is a lot of variety in the terrier group, though—from fuzzy, 70-pound Airedale terriers to smooth-coated, 25-pound Boston terriers. Terriers were originally bred to hunt small animals like rats and foxes. Terrier comes from the Old French chien terrier, or "earth dog," a reference to the terrier's willingness to follow its prey into underground burrows if necessary.
