Meet six month-old sheep Jack, who goes around a Shropshire farm thinking he is a dog.
Jack lives at Adderley Wharf Farm near Market Drayton.
And his owners claim he has become so attached to their nine-year-old springer spaniel Jessie, he has ended up acting like it.
The farm belongs to Alison Sinstadt and her partner Simon, who say the two animals have become so attached they go for walks together along the canal and sleep in the same box.
It comes after bosses at Telford security firm RMP Guarding revealed a pair of protective parrots had been proving effective guard dogs after learning how to bark.
Alison said: "He was born one of three lambs, which is quite rare. He was very small and we decided to bring him in the house and put the hairdrier on him and forced him to drink milk.
"It ended up that he took to the dog and they now sleep together outside in a box."
