types began in earnest, but mixing of the two types in some cases still exists today. When the types were separated by the Rat Terrier Club of America, the short-legged variety was named in honor of Theodore Roosevelt, although he never owned Rat Terriers nor was he instrumental in developing the Teddy Roosevelt Terrier. The dog most attributed to being one of the foundations for the Rat Terriers was a black-and-tan, mixed-breed, feist-type dog owned by the Roosevelts. In one of his letters to his children, President Roosevelt writes, "There is a very cunning little dog named Skip, belonging to John Goff's pack, who has completely adopted me. I think I shall take him home to Archie. He likes to ride on Dr. Lambert's horse, or mine, and though he is not as big as Jack, takes eager part in the fight with every bear and bobcat." Often confused with Skip the black and tan feist, the Roosevelts also had a dog named Scamp. Scamp is the only dog mentioned in Roosevelt's letters as ever hunting rats while in the White House, "Scamp is really an extraordinary ratter and kills a great many rats in the White House, in the cellars and on the lower floor and among the machinery. He is really a very nice little dog." Unfortunately, no pictures of Scamp nor descriptions other than one which describes him as a Fox Terrier have been found. Another terrier which often is confused with the Rat Terrier was Roosevelt's dog named Jack. In Mr. Roosevelt's letter dated July 27, 1902, to Mrs. Roswell Field, he writes, "It is a real pleasure to send you a photograph of my boy Kermit, with Jack, the Manchester Terrier, who is absolutely a member of the family." Jack was a Manchester Terrier, not a Rat Terrier. The first standard for the breed was developed by the now-defunct Teddy Roosevelt Terrier Club of America in 1996. Currently, several registration organizations are active, all of which have their own standards, but the most commonly accepted are the United Kennel Club and the United Kennel Club International, although the UKCI still only recognizes them as a variation of the Rat Terrier. In 1999, both "Rat Terrier" and “Teddy Roosevelt Terrier" were accepted as a separate breeds by the United Kennel Club. Currently, the UKC accepts single Teddy Roosevelt Terrier registration applications for dogs from 10 different
