"You're a good dog, Rita. Definitely a good dog."

Runt is an unintelligent, happy-go-lucky big dog. He accompanies a cat, Rita, who he believes is a stray dog like him.

He is voiced by Frank Welker.


Runt is extremely dimwitted, believing from the time Rita met him that she was another dog. This is largely to Rita's advantage, since he would behave hostilely towards any cats.

Despite his simple mind, he has great affection for Rita, letting her insults and disdain slide off of him. Runt (usually) intermediately expresses worry and stress when he thinks she is in danger. He even went to the point of biting a man who was trying to cook Rita, and grabs her by the scruff to safety when he assumes they are in danger (although usually incorrectly, to Rita's annoyance). He is also, in his rare moments of coherency, surprisingly attached to Rita, but when she is about to leave on a train to a nice home and he is left behind, he seems sad. However, Rita quickly jumps off the train, much to his surprise and delight.

  • Runt's voice is Welker’s impression of Dustin Hoffman's character from Rain Man.
  • Runt can often show he has some of Rita's big traits. Though he usually sticks to standing on his four legs. In Phranken-Runt, Witch One and Wakko's Wish, he stands on his hind legs and acts around it the way Rita does. Runt can even sing, as shown in Les Miseranimals and Of Nice and Men.
  • He and Rita will not be appearing in the 2020 series.
