Shingle disturbed by crossword compiler’s dog (7,6)
I believe the answer is:
english setter
'dog' is the definition.
(English setter is an example)
'shingle disturbed by crossword compiler's' is the wordplay.
'disturbed' is an anagram indicator.
'by' says to put letters next to each other.
'crossword compiler' becomes 'setter' (I've seen this before).
'shingle' is an anagram of 'english'.
'english'+'setter'='ENGLISH SETTER'
(Other definitions for english setter that I've seen before include "Dog -- serenest light (anag)" , "canine" , "One in white coat spotted" , "man responsible for language exam" , "Breed of dog" .)
