dug

Dug is the past tense and past participle of the verb dig, used to indicate that someone or something has excavated or removed material by digging. It is an irregular verb; for example, "They dug a trench yesterday." In addition to its verb form, Dug is used as a proper name or nickname. It is commonly a shortened form of Douglas or Dugald and may be used as a given name for men in English-speaking countries.

In popular culture, Dug is the name of the canine character in Pixar's animated film Up (2009). Dug is a friendly, talking Golden Retriever whose thoughts are translated into speech by a device on his collar; he accompanies the film's protagonists and is characterized by his cheerfulness and loyalty.

The term may also appear in other contexts as an informal label or nickname within communities or fiction. Outside of language use, there are few standardized meanings for "Dug" beyond the verb form and as a personal name, and it should be understood from context.
