Ren and Stimpy (characters)
Ren and Stimpy, created by John Kricfalusi, are the titular characters in the American animated television series The Ren & Stimpy Show. Kricfalusi created the characters during his stay in Sheridan College and they first appeared on film in the pilot episode "Big House Blues". Ren is a scrawny, violently psychotic chihuahua, and Stimpy is a fat, stupid cat. They are often at odds with each other on the show, though they do share moments of closeness together.

Ren is a scrawny "asthma-Hound" Chihuahua. Martin "Dr. Toon" Goodman of Animation World Magazine described Ren as scrawny, dyspeptic, and violently psychotic, who loses his mind occasionally in a cumulative process resulting in him becoming, in Goodman's words, a "screaming klaxon, neon-pink eyes dilating into twin novae inches above his jagged, monolithic teeth." Andy Meisler of The New York Times described Ren as "adventurous," "intelligent," and "emotionally brittle."
Ren has a fairly long, rat-like, pink tail. However in the first two seasons, Ren's tail constantly disappeared and was even docked by George Liquor in the season 2 episode "Dog Show", while getting Ren and Stimpy both ready for an upcoming dog show (even though Stimpy is a cat) although it continued to appear afterwards in the episode, as well as episodes afterwards. After season 2, Ren's tail had a rare form of continuity throughout the show, not even appearing at all in most episodes.
