The 68-year-old '9 to 5' hitmaker had offered to care for a pooch found at the festival site - where she performed to a crowd of 150,000 last month.
While she is pleased the canine, which workers named after her, has been reunited with its original owners by the Happy Landings Animal Shelter, she says she had been looking forward to having a new pet, reported Contactmusic.
"We got a call from the main people with the government and they told us that the true owners did come forward. There was a language barrier; I think they were from another country. They got the dog back so I don't get to take her home. I was looking forward to it," Parton said.
