Fruit that makes dog rave (7)

Ross

I believe the answer is:

'fruit' is the definition.
(currant is a kind of fruit)

'dog rave' is the wordplay.
'dog' becomes 'cur' (cur is a kind of dog).
'rave' becomes 'rant' (synonyms).
'cur'+'rant'='CURRANT'

'that makes' is the link.

(Other definitions for currant that I've seen before include "Product of grape", "Small black raisin", "Something ideal for jamming", "Small dried seedless grape", "Cake ingredient".)
