While the rest of the flock at Heckley High House is grazing in the fields, Cora keeps her distance in her own paddock and happily goes out for walks with the dogs.
And Cora will jump out if she finds herself in the same field as other sheep.
But despite this anti-social trait, Cora is very affectionate towards owner Emily Wakefield, 16, and Holly, a rough cross Border collie.
Emily's mother Juliet said: "Cora doesn't associate with other sheep at all.
"She would rather go in the garden.
"She sometimes gives my daughter a kiss and she head butts the dog. The dogs clean and lick her.
"Cora has been coming for walks with us ever since she was big enough."
Cora was born in April and because Emily helped out during lambing time farmer's son Lance Green gave her the animal to keep as a pet.
From the day she was born she has been bottle-fed milk every two hours and has only recently been weaned off it.
Juliet, 46, said: "Cora has only been off the bottle for about two months as she is very fond of it and I think Emily was rather fond of feeding her with it too."
Cora now eats grass and hay and is quite partial to the odd flower or two from the garden.
The family, who live in Alnwick, also keep a horse on the farm and have a Kune Kune pet pig called Portia, four, who belongs to Emily's older sister Kathryn, 19.
When asked how fond the family is of Cora, Juliet said: "I think attached is a good word, she will definitely be kept as a pet."
She said she was named after the heroine Cora Munro, a character in Emily's favourite film: The Last of The Mohicans.
