Washington, Jan 16 : PETA bosses have launched a probe to find out the truth behind reports suggesting Beyonce has abandoned her pet dog.

According to reports on the Internet, last year the `Baby boy' singer dumped five-year-old Shih Tzu with staff at her New York record company, and never came back to claim it.

Sources revealed that employees at the record label have been looking after the dog ever since.

"They are taking turns to take Munchie for walks and take it home on the evenings and weekends," Contactmusic quoted a source as telling MusicToob. com.

The source added: "Everyone realises that Beyonce has been incredibly busy recently, recording and promoting her Sasha Fierce album. But the whole team will be glad when she eventually takes charge of the dog for herself again."

Prompted by the report, the animal rights group has decided to investigate whether or not Beyonce really has just dumped her dog.

"We have an inquiry in with Columbia," said a spokesman. (ANI)
