Tibetan beast (3)
I believe the answer is:
yak
'tibetan beast' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yak that I've seen before include "Long-haired ox of central Asia" , "Long-haired ox of Tibet" , "Beast of burden" , "Shaggy Tibetan ox" , "Gossip (sl)" .)
