Political satirist Mark Howard filed the petition Tuesday on behalf of his terrier, Dylan Westie, KTVT-TV, Dallas/Fort Worth, reported.
Howard said he has been hanging out at a local coffee shop listening to Irving residents talk about infighting on the Irving city council.
"You have two factions doesn't seem to be getting anything done ... that needs to be done," he said.
That's when he decided to nominate his dog for mayor.
"If you look at all the cat fighting, what better way to solve a cat fight than get a dog in the mix," said Howard.
However, the city said that because Dylan isn't a registered voter, he doesn't qualify to be on the ballot.
