Talk of a shaggy animal (3)
I believe the answer is:
yak
This clue is a double definition.
'talk' is the first definition.
(I know that talk can be written as yak)
'a shaggy animal' is the second definition.
(I've seen this in another clue)
'of' acts as a link.
(Other definitions for yak that I've seen before include "Tibetan ox - chatter" , "Wild ox" , "Pack animal" , "Gossip; ox" , "Tibetan creature" .)
