Garden seat designed for dogs (5,5)
I believe the answer is:
great danes
'dogs' is the definition.
(Great Dane is an example)
'garden seat designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'garden'+'seat'='gardenseat'
'gardenseat' anagrammed gives 'GREAT DANES'.
'for' is the link.
(Other definitions for great danes that I've seen before include "Large dogs" , "Pets" , "Animals" , "big 6 downs [PET]" .)
