Tender saga involved dogs (5,5)
I believe the answer is:
great danes
'dogs' is the definition.
(Great Dane is an example)
'tender saga involved' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'tender'+'saga'='tendersaga'
'tendersaga' with letters rearranged gives 'GREAT DANES'.
(Other definitions for great danes that I've seen before include "big 6 downs [PET]" , "Large dogs" , "Pets" , "Animals" .)
