Cook (11 November 2000 – 19 May 2016) was a Jack Russell Terrier dog actor known for his role as Pancho in the advertisement of Lotería Primitiva of Spain, in which he earned 500 euros per day of shooting.

[1] He was born in Casteldefels, Barcelona, and his owner was Antonio Valor, his trainer, and his wife Yolanda.

At the age of four months, he was sold for 70,000 pesetas and they decided to change his name to Cook (his original name was Lucke and it sounds too musical).

[3] In 2003, he played Valentín in the TV series Aquí no hay quien viva, which is the mate of Vicenta Benito (Gemma Cuervo).

[8] The advertising campaign he worked on was awarded the Gran AMPE de Oro and the Premio a la Excelencia Publicitaria, given by Museo Reina Sofía.
