Focus on White Greyhound of Richmond and discuss the Description.
According to the Cambridge University Heraldic and Genealogical Society:
"The White Greyhound of Richmond bears a shield of Tudor livery, white and green, with a Tudor Rose ensigned by a Royal Crown. Henry VII sometimes used greyhounds as supporters and on his standards. His father, Edmund Tudor, was created Earl of Richmond and the white greyhound was associated with the Honour of Richmond. The rose in the badge shows the association of the red and the white elements of Lancaster and York respectively, emphasising the union of the rival houses."
