Logo (April 3, 2000-November 22, 2010)
Visuals: On a yellow marble background, we see a crudely drawn dog with a star on his right eye. Then his tongue pops out that causes a rude look on his face and a thought bubble appears above, meaning that he's thinking really hard. The words "Sirius Thinking Ltd." fade into the thought bubble. Then the dog returns to normal and smiles, as "For Jon, Jim, Joe, Jeff, Jeanne... and Ted" appears below the dog and thought bubble with text.

Trivia:
 * The company is likely named after the brightest star in the night sky of the same name. Said star is also inside the Canis Major (Greater Dog) constellation, hence why the dog has a star on its eye.
 * The names shown below the dog (Jon, Jim, Joe, Jeff, Jeanne, Ted) might refer to (longtime director and writer for Sesame Street),,  (songwriter and composer for Sesame Street), and  (longtime writer for Sesame Street). Some think "Ted" could be referring to Theodor Geisel (most known as ), and the meaning of "Jeanne" is unknown. This is all merely speculation, as no official statement has yet been released by the company regarding this.

Variants:
 * On seasons 9 and 10 of Between the Lions, the dog is drawn even more crudely (with added text below saying "© SIRIUS THINKING"), the background is simplistic and the "For Jon, Jim, Joe, Jeff, Jeanne... and Ted" tagline is already in its place. After a moment, the thought bubble appears with the text "Sirius" on the inside and "Ltd." mostly on the outside. After another moment, the "(thinking)" text appears as well. Finally, the inside of the star around the dog's eye becomes yellow.
 * An in-credit version exists where the logo is next to the WGBH logo.

Technique: 2D computer animation. Limited animation for the later variant.

Audio: A rude noise made by the dog when he sticks out his tongue, then a cackle. This is sometimes combined with the Between the Lions closing theme.

Audio Variant: From 2006 to 2010, the dog says "whee" instead. The original audio variant, however, was used again on Lomax, the Hound of Music.

Availability: Seen on Between the Lions and Lomax, the Hound of Music. It is preserved on VHS, DVD and streaming prints of the former show.
