and utilized virtual bone-structure in the CGI models. Personality-wise, the new Bolt would be more naïve and insecure, conveying more pathos than Henry. At the same time, the art department worked to give Bolt a whimsical nature with a pose that excels confidence, thus allowing the character to have a contrasting personality and body language which reflects that. Voice work John Travolta was chosen to do the voice work for Bolt. Despite a history of turning down voice-over offers for animated characters, he agreed to provide the voice for Bolt as he, according to the actor himself, "indicated as the right character".

The "normal" Shepherd has longer, thinner legs and a more meager appearance. Bolt's coat is a creamy white and his fur differs in thickness as it is short haired over his belly, flanks and back, and a bit thicker over his neck. The animators worked much with Bolt's
