Captain (The Stuff of Nightmares)

Captain was a wild dog from the Middle Ages whom the Fourth Doctor kept as a pet at Nest Cottage. He was later given to Mike Yates.

Meeting the Doctor
The Doctor met Captain in England in the Dark Ages. Captain led a pack of wild dogs possessed by the Hornets. Once freed from their control, he helped the Doctor track them in the TARDIS. The Doctor took him to Nest Cottage as he had done with others the Hornets had possessed.

Leaving the Doctor
The Doctor gave Captain to Mike Yates to look after once the Hornets had been defeated. The Doctor already had a dog aboard the TARDIS and he did not think the two would get along.

Reunion with the Doctor
The following Christmas, Captain and Mike returned to Nest Cottage to visit the Doctor and Fenella Wibbsey. The two became embroiled in another of the Doctor's adventures. (AG: Hornets' Nest, Demon Quest)
