Sherlock - Actual name of the basset hound to which Elvis Presley sang "Hound Dog" on the July 1, 1956 episode of THE STEVE ALLEN SHOW. Locked in a ratings war with Ed Sullivan, comedian Steve Allen hired the talents of a young and upcoming singer Elvis Presley to perform on his program. Dressed in white tie and tails Elvis sang (without shaking) to Sherlock who wore a top hat. Elvis and RCA used Sherlock for publicity in the 1950s.
