'hunting accessory' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'horse carrying loose' is the wordplay.
'horse' becomes 'gg' (geegee or GG is a childish term for a horse).
'carrying' indicates putting letters inside.
'loose' becomes 'undo' (I've seen this before).
'gg' going around 'undo' is 'GUN-DOG'.
