Dogcow
The dogcow, named Clarus, is a bitmapped image designed by Apple for the demonstration of page layout in the classic Mac OS. The sound it makes is "Moof!", a blend of "moo" and "woof". Clarus became the archetype of surrealistic humor in the corporate culture of the original Macintosh group, particularly as the mascot of Apple’s Developer Technical Support as officially documented in Technote #31.
History
In 1983, the dog icon had been created by Susan Kare as the glyph for "z", as part of the Cairo font. Later, when redesigning the classic Mac OS "Page Setup" print dialog box for the LaserWriter, an example image was required. According to HCI engineer Annette Wagner,The new dog graphic had a more bovine look.
On October 15, 1987, the term "dogcow" was coined by Scott Zimmerman. She was later named Clarus by Mark "The Red" Harlan, as a joking reference to Claris, Apple's business unit for office software at the time.
The Clarus icon became one of the giant pieces of pixel art in the Icon Garden in the front yard of the Apple Campus at 1 Infinite Loop; the Icon Garden has since been removed.
Apple's Developer CD Series of the 1980s features a dogcow logo on the discs.
The latest references to the dogcow came in the documentation for the Swift programming language, which uses the word "dogcow" as an example of the use of Unicode characters to name constants and variables; and in a sticker pack in Messages.

In the first beta of macOS Ventura, the dogcow returned to the page setup window, and in iOS 16 entering 'Clarus' or 'Moof' results in the keyboard suggesting the 'dog' and 'cow' Emoji.
