Hairy at the heel
I can’t say I ever liked him, and I’ve once or twice had a row with him, for he used to bring his pals to shoot over Dalquharter and he didn’t quite play the game by me. But I know dashed little about him, for I’ve been a lot away. Bit hairy about the heels, of course
The phrase is also used by the English novelist Agatha Christie, as well as the critic Walter James Macqueen-Pope, who in Back Numbers (1954), described someone as, “a cad, a bounder, an outsider, hairy at the heel.” Putting it simply, a person who was ill-bred.
The idiom also appears as ‘hairy round the heels’, ‘hairy in the fetlocks’, ‘hairy-heeled’, or just simply ‘hairy’. It is not widely used today.
