The Wire Fox Terrier (also known as Wire Hair Fox Terrier or Wirehaired Terrier) is a breed of dog, one of many terrier breeds. It is a fox terrier, and although it bears a resemblance to the Smooth Fox Terrier, they are believed to have been developed separately. Although it is said Queen Victoria owned one, and her son and heir, King Edward VII, did own a wire fox terrier named Caesar, the breed was not popular as a family pet until the 1930s, when The Thin Man series of feature films was created. As of 2019, the wire fox terrier has the distinction of having received more Best in Show titles at Westminster Kennel Club dog shows (currently 15) than any other breed.
