George Rose's final film. On May 5, 1988, Rose's adopted son and three other men beat Rose to death. Ironically, Jose Menendez, one of the executives in charge of production for this film, was also murdered by his two sons over a year after Rose's death.
Distributor TriStar's first animated feature.
Bright Eyes now wears her original green shirt but has white fur and a yellow skirt.
Howler now has curly, brown hair, a red shirt, and a green derby. Although he still howls, he is no longer the bravest puppy of the group.
Cooler now wears a white leather jacket and no longer sports his trademark Eddie Murphy-style laugh. During the "Let's Go to the Pound" segment, he wears his favorite pair of sunglasses. He is somewhat more serious than he was in the TV Series.
