In 1982 Pedigree, then known as Kal Kan, made a commercial with Ray Perry and his Kerries. The featured dog was Ray's favorite bitch, the only bitch that he said would never be for sale. Her name was Ch. Tontine's Gillian ("Gilly").
The video was filmed along Lake Matthews in Southern California.
Thanks to Lou Perry and Marilyn Garrett we have a copy of the commercial for your viewing.
