Hotel California performer following Black Dog (6)
I believe the answer is:
beagle
'dog' is the definition.
(beagle is a kind of dog)
'hotel california performer following black' is the wordplay.
'hotel california performer' becomes 'eagle' (Hotel California is an Eagles song).
'following' is a charade indicator (letters next to each other).
'black' becomes 'b' (as in pencil classifications).
'eagle' after 'b' is 'BEAGLE'.
(Other definitions for beagle that I've seen before include "5 [MANS BEST FRIEND]" , "Small short-legged hound" , "Small hunting dog" , "Type of hound" , "Small, sturdy breed of hound" .)
