Dog tired is an old English idiom usually hyphenated to dog-tired. An adjectival phrase meaning to be physically exhausted, it derives from an ancient tale of Alfred the Great, who used to send his sons out with his widespread kennels of hunting dogs. Whichever of his sons, be it Athelbrod or Edwin, were able to catch more of the hounds would gain their father’s right-hand side at the dinner table that evening. These chases would leave them ‘dog-tired’ yet merry at their victory. The tradition was continued for a few generations but is not noted in literature after Bede’s Ecclesiastical History of the English People.
