As a high schooler, Dindal went to Jamesville-DeWitt High School, in which he attended most of the art classes that the school had offer. Dindal learned animation at CalArts. He began working at Disney in 1980. His work included The Fox & the Hound (1981), The Black Cauldron (1985), Mickey's Christmas Carol (1983), and The Great Mouse Detective (1986), each following a very similar animation style in all the films. This style consisted of similar backgrounds with delicate animation and complex character effects, and was well received.
After these projects, Dindal left Disney around 1986 to briefly work on outside projects with Filmation and worked on projects like BraveStarr and The Brave Little Toaster. He returned to the studio in 1987 and got his first head role as a visual effects supervisor for The Little Mermaid (1989). He later worked as head Animator for the film The Rescuers Down Under (1990). He directed the animated segment for the live-action film The Rocketeer (1991), and worked as an effects Animator on the animated film Aladdin (1992).
Dindal's directorial debut was Cats Don't Dance, which was released in 1997, three years before The Emperor's New Groove was released in 2000. In Cats Don't Dance Dindal voiced Max. The film won the Annie Award for Best Animated Film and Dindal was nominated for directing. The Emperor's New Groove was initially expected to be a classic Disney musical feature called Kingdom of the Sun. However, the idea didn't work out, and Dindal, along with Chris Williams and David Reynolds, changed the script to a comedy. During the six-year production, he started to work on Cats Don't Dance, a Turner Broadcasting (since merged into Warner Bros.) animated musical production.
Dindal worked on Chicken Little (2005), another Disney production, which needed a large animation team. Dindal voiced Morkubine Porcupine and Coach in the film. The film was nominated to several Annies, though Dindal was not nominated as a Director. During the film's production, DisneyToon Studios produced Kronk's New Groove as a direct-to-video feature. As Dindal was working on Chicken Little at the time, he did not have a position on the staff. Later, Dindal created the TV series The Emperor's New School (2006-2008).
In March 2006, a day after the DVD release of Chicken Little, Dindal and Producer Randy Fullmer left the company because they were reportedly tired of dealing with then-WDFA head David Stainton. In the next few years, Dindal was attached as a Director to several live-action films, including Sherlock's Secretary, Kringle, and Housebroken. By December 2010, Dindal was directing at DreamWorks Animation an animated feature film titled Me and My Shadow, which would combine both computer and traditional animation. By January 2012, he was no longer directing the film, which went in 2013 back into development. In July 2014, he was credited as the Illustrator for a documentary called Restrung, which is focused on Fullmer, a collaborator that worked with him at Disney and Filmation, with his career at Wyn Guitars from 2006.
