Keown started working in comics in 1986 drawing several series for Aircel Comics, including Samurai, Elflord, Dragon Ring (later Dragonforce), and Warlock 5.
Keown moved to Marvel Comics in 1989, where he first worked on Nth Man: the Ultimate Ninja, before replacing Jeff Purves on The Incredible Hulk. Keown worked on Hulk with writer Peter David, creating one of the more memorable runs of the book. David has named Keown one of the three artists whose art has mostly closely matched the visuals he conceived when writing a comic book scripts (the others being George Pérez and Leonard Kirk).
He left in 1993, to start publishing his self-created Pitt at Image Comics. In 1995, publication of Pitt was moved over to Keown's own company, Full Bleed Studios.
He eventually began working for other companies once more, drawing The Darkness for Top Cow and teaming up with Peter David once more with Hulk: The End for Marvel. Keown also drew a crossover featuring The Darkness and the Hulk.
Keown drew many of the pictures for the Hulk memorabilia that was released to coincide with the 2003 feature film Hulk.
In 2009 Keown illustrated the three-issue crossover of The Darkness / Pitt, which was written by Paul Jenkins. It was preceded by a special preview book released in December 2006.
Keown worked with Milo Ventimiglia on Top Cow Productions' Berserker, which premiered June 2009.
Dale has also worked over the years with both Marvel and DC Comics.
