Pa Kettle, a search and rescue dog, picked up 2,387 votes - 55 more than Keyni, a wolf, who will be deputy mayor in the town of Divide, Colorado.
Buster the cat, who placed third with 1,790 votes, is the viceroy, 'The Gazette' reported.
Divide does not have a human civic leader, so Teller County Regional Animal Shelter holds an unofficial online mayoral race to raise funds.
Pa will replace Walter the three-legged cat, who will retire.
The mayoral inauguration is to take place later this week.
