Beyonce Knowles has abandoned her award-winning dog, Munchie.

Staff at Columbia Records, Bey’s label, are said to be livid that the “Single Ladies” hitmaker has left Munchie at their offices since last summer.

Annoyed staffers have been forced to clean up after the unhousebroken pooch.

“Puddles of liquid are appearing all over the office.”

“Munchie has effectively taken up residency. Beyonce left the dog here towards the end of last summer and hasn’t returned to pick Munchie up,” a source at the label told The British Sun Wednesday.

“Staff are taking turns to take Munchie for walks and take it home on the evenings and weekends.”

In 2005, Munchie was named America’s Most Eligible Pet by Animal Fair Magazine.
