The phrase refers to the hairs on the neck and it may have been used in the military. It was first used by Rudyard Kipling in The Drums of the Fore and Aft from 1890, regarding the British Army's occupation of India:
"They'll shout and carry on like this for five minutes. Then they'll rush in, and then we've got 'em by the short hairs!"
The meaning of the phrase changed when L. Dorothy Slayers in her collaboration with Robert Eustace in her novel Doctors in Case from 1930 wrote:
“She’s evidently got her husband by the short hairs.”
Since then, the phrase has been used in different variants.
