Buc-ee's argues that Super Fuels logo of a brown dog wearing a red cape and smiling in front of a blue background mimics its popular logo.

Super Fuels is an Irving-based gas station chain with an anthropomorphic dog mascot that Buc-ee's argues is a copy of their trademark beaver mascot.

Late last year, the chain sued a Missouri gas station, Duckees Drive Thru, arguing that its cartoon duck was a copycat of the beaver. It has also accused convenience stores in Mexico of copying its logo, including BUK-II’S Super Mercado and Lucky’s.
