Dukey

Universe: Johnny Test

Debut: Johnny Test - "Johnny to the Center of the Earth" (2005)

Johnny's anthropomorphic 16-year-old talking pet dog and lackey. The cause of Dukey's anthropomorphism is because of one of Susan and Mary's inventions, thus giving him humanlike abilities. Dukey, when Mrs and Mr Test aren't around, will stand on his hind legs rather than all fours, like he does when Johnny's parents are around. The reason for this is that Mr. Test banned Susan and Mary from DNA experiments, which was how they gave Dukey human-like intelligence.

There have been a few "close calls," such as when Mr. Test got trapped inside of one of Johnny's video games and Johnny and Dukey also went inside the game to rescue him, and Dukey accidentally spoke in front of him, causing Mr. Test to ask, "Did Dukey just talk?" Every time one of his parents asks this question after Dukey just spoke in front of them, either Johnny, Susan, or Mary answers "no" and their parents immediately believe them. Sometimes Dukey dresses as a human being when going out in public.
