Jean-Jacques Saint-Dremaine Duprix, a.k.a. Jacques, is a prize-winning, pampered Jack Russell Terrier belonging to a stuck-up, rich boy named Preston Price in Disney's Life Is Ruff. When Preston gives Jacques a command, Preston speaks to him in French with a rusty, nerdy, and annoying accent. Jacques is often referred to as a cute dog when in fact, he is a mean dog who only loves and obeys his master and likes to provoke harm to others like Calvin and Tyco.
