Kathleen Florence May Pelham-Clinton, Duchess of Newcastle-under-Lyne OBE (née Candy; 1872 – 1 June 1955), was a well-known conformation show judge and dog breeder who influenced the Borzoi and Wire Fox Terrier breeds.

Born in 1872, the future Duchess was the daughter of Major Henry Augustus Candy by his marriage to Hon.

Prior to the marriage, Kathleen was already a judge and dog show exhibitor, primarily of Fox Terriers.

[5] The Duchess was first introduced to dogs when her mother was given a Borzoi named Spain as a gift from the Spanish Marquis of Quandelmina.

[5] Sixteen of Tsar Nicholas II of Russia's Borzois were brought to England to participate in Crufts in 1892, and although they were described as "badly constructed", the Duchess purchased Oudar, thought to be the best of the lot, for £200,[5] a sum equivalent to £19,818 in 2010.

Podar of Notts was one of the most influential Borzois of all time, and the majority of modern dogs of the breed can be traced back to him in some way.

[7] Between 1900 and 1923, the Duchess bred twelve Wire Fox Terrier champions, the first being the highly influential Ch.
