Dog in shelter gets agitated (7,6)
I believe the answer is:
english setter
'dog' is the definition.
(English setter is an example)
'in shelter gets agitated' is the wordplay.
'agitated' is an anagram indicator.
'in'+'shelter'+'gets'='insheltergets'
'insheltergets' anagrammed gives 'ENGLISH SETTER'.
(Other definitions for english setter that I've seen before include "Dog -- serenest light (anag)" , "man responsible for language exam" , "One in white coat spotted" , "Breed of dog" , "canine" .)
