Etymology

The word "doggo" is a playful, informal variant of "dog," originating from internet culture (early 2010s). The suffix "-o" is a colloquial augmentative or affectionate marker, often added to words for humor or endearment (e.g., "kiddo," "weirdo"). Unlike traditional morphemes, "-o" here doesn’t carry a fixed meaning but serves to amplify the word’s casual or whimsical tone. The term reflects the internet’s tendency to anthropomorphize pets with exaggeratedly cute or lazy traits ("doing a relax," "heckin’ bamboozle").

Examples
  1. Look at that fluffy doggo sleeping on the couch!

  2. My doggo always greets me with a wagging tail.

  3. "Why is your doggo wearing sunglasses?" "Because he’s a cool pup!"

  4. The internet loves photos of happy doggos.

  5. After a long walk, the tired doggo plopped down on the rug.
