Tiny Toon Adventures

Tiny Toon Adventures is a cartoon series created by Tom Ruegger and executively produced by Steven Spielberg. It originally ran from September 1990 to May 1995. In 1993, it was spun off into Animaniacs, a show centering around three characters that the Tiny Toons encounter in one episode.

The series follows the many antics of a group of younger counterparts to the popular Looney Tunes characters, all students of the Acme Looniversity, set up by the original characters themselves to teach cartoon characters lessons on comedy.

Prom-ise Her Anything
Season 1, Episode 17 Airdate: October 8, 1990

In the episode, the first appearance of Arnolda (also voiced by Tress MacNeille) is a tall, white female pitbull with black hair, huge muscles and is seen wearing a red dress in the episode. She was the love interest and prom date of Arnold (a muscular male pitbull). Arnold was the one who had arrived to introduce her as his date to Buster Bunny and claimed that she was the only girl who looked better than him.

 Trivia 

One can assume that Arnolda could be from Romania just as Arnold himself as no one had ever seen her before until she came to the prom.
