'Everyone seems to be talking about the new series so the team decided to name them after some of the cast'
The litter were discovered abandoned in a cardboard box by a woman walking her own dogs in a park in Southampton.
She took the dogs to the nearby Blue Cross rehoming centre, where staff decided on the names in the hope it would help them find new homes for the neglected pups.
Hugh Bonneville and Elizabeth McGovern, who play the Earl and Countess of Grantham, are represented by dogs Earl and Cora.
Other characters include Jim Carter's Carson, Laura Carmichael's Edith, Allen Leech's Tom and Sophie McShera's Daisy.
Ed Speelers' Jimmy, Matt Milne's Alfred and Shirley MacLaine, who plays Martha Levinson, are also represented.
Laura Boyle, rehoming supervisor, said: 'Everyone seems to be talking about the new series so the team decided to name them after some of the cast.
'We hope they will be just as popular with potential new families when they go up for rehoming.'
She added: 'We don't know how long they had been abandoned for but they were all very hungry and thirsty.
'She brought them to us where we gave them all a good check-up and they seem to be in good health.
'After a tasty meal they felt much better and are typical bright and bouncy pups.'
