What is the name of Arthur Hobbs's dog?

Arthur Hobbs’s dog is named Tugboat. The name appears in Arthur’s character description alongside his reputation as the shouting boss known as “Artillery Arthur.”

Tugboat is a small but distinctive detail in Arthur’s characterization. Arthur is not one of the show’s main five friends, so details about his home life and pet are easy to overlook, yet they help make the otherwise intimidating executive more recognizable beyond the workplace.

This answer is commonly mixed up with names that sound like plausible sitcom pets, such as Rufus, Biscuit, or Scout. It can also be confused with Arthur’s own nickname: “Artillery Arthur” describes his tendency to yell at employees, while Tugboat is exclusively the name of his dog. Arthur is portrayed by Bob Odenkirk and appears across several workplace-related storylines involving Marshall.
