Chewy, was Boomer and Brady's dog when they lived in Chicago. He only appeared in a narrative flashback in the episode Beach Party Maggot Massacre.
History[]
Boomer and Brady were having a big party. While Boomer, Brady, and the guests were dancing, Chewy got into the "Extra Spicy Party Mix," which caused him to puke into a fan. Chewy's puke flew everywhere; which led to the guests referring to the party as "The Barf Fiesta."
