As of this series, Steven Weber is the only actor to portray Charlie more than once.
The opening credits show clips from "All Dogs go to Heaven 2," and then a shot of Killer, who had not appeared since the original movie.
Starting in late 1997 and early 1998, the animation improved.
Season 3 has 14 episodes, unlike previous seasons, which had 13.
In season 3 the episodes are shortened, this due to the new intro and ending credits.
