Dog born to help (6)
I believe the answer is:
basset
'dog' is the definition.
(type of dog)
'born to help' is the wordplay.
'born' becomes 'b' (common abbreviation).
'to help' becomes 'asset' (an asset can be a help).
'b'+'asset'='BASSET'
(Other definitions for basset that I've seen before include "Short-legged dog" , "Short-legged hound used for hunting (6)Short-legged hound used for hunting" , "Hound (named Fred?)" , "Sturdy hunting dog" , "Type of hound" .)
