Lupo is the name of Kate and William's black English Cocker Spaniel. Lupo, who was gifted to the royal couple in 2011 just after their wedding, has been a loyal and cherished member of their family ever since. Kate and William have often been seen with Lupo in public and even included him in some of their official portraits. The name Lupo is derived from the Italian word for wolf, which is a fitting name for a dog.
