Continuing to wring revenue from a tired premise, the family dogs throw in their two cents in the second sequel to "Look Who's Talking." For anyone who thinks Diane Keaton's hair makes her look a little like a hound dog, here's a chance to visualize her as a similarly long-eared poodle with an attitude. DeVito is also cast in character as the voice of a rough street-smart mutt, who happens to get thrown into the same household as the bosses' pure-bred poodle. Sparks, Alpo, and butt jokes fly as the dogs mark their territory. Meanwhile, dimwit wife Alley is worried that husband Travolta is having an affair, and is determined to get him back.
