Food around strange dog, say (7)
I believe the answer is:
crumpet
'food' is the definition.
(I know this)
'around strange dog say' is the wordplay.
'around' becomes 'c' (abbreviation for 'circa').
'strange' becomes 'rum' (similar in meaning).
'dog say' becomes 'pet' (dog is an example).
'c'+'rum'+'pet'='CRUMPET'
(Other definitions for crumpet that I've seen before include "Light, soft yeast cake" , "Muffin" , "teatime treat!" , "Thick soft cake eaten toasted and buttered" , "Thick, soft porous cake for toasting" .)
