A man who was induced into a coma after his genitals were savaged by an Olde English Bulldogge "was alone in the room with the animal" when the incident happened.
The man, who has not been named, was also alleged to have "applied peanut butter, or another food spread" onto his crotch area before his genitals were bitten off by the animal, a police source told The Times.
Police in East Lothian, Scotland were alerted after the 22-year-old man was found unconscious and fully clothed in a pool of his own blood in a flat in Haddington in September, according to the Daily Mail.
He was then taken to Edinburgh Royal Infirmary, however his organs could not be reattached, as they had been eaten by the dog.
His condition later stabilised and he was then transferred to the Western General Hospital where he has since been assisting police with their enquiries.
