The story

Inherited from Middle English dogge (akin to Scots dug), from Old English dogga, docga, of uncertain origin.uncertain The source flags this step as uncertain. The original meaning seems to have been a common dog, as opposed to a well-bred one, or something like 'cur', and perhaps later came to be used for stocky dogs. Possibly a pet-form diminutive with suffix -ga (compare frocga (‘frog’), *picga (‘pig’)), appended to a base *dog-, *doc- of unclear origin and meaning.uncertain The source flags this step as uncertain. One possibility is Old English dox (‘dark, swarthy’) (compare frocga from frox). The theory goes that it could have been an epithet for dogs, commonly used by children, meaning "good/useful animal".disputed Scholars disagree here; the competing view is quoted as the source gives it.
