Bird touring Spain mistaken for dog (6,7)
I believe the answer is:
cocker spaniel
'dog' is the definition.
(cocker spaniel is a kind of dog)
'bird touring spain mistaken' is the wordplay.
'bird' becomes 'cockerel' (cockerel is a kind of bird**).
'touring' indicates putting letters inside (touring can mean going round).
'mistaken' is an anagram indicator.
'spain' anagrammed gives 'spani'.
'cockerel' placed around 'spani' is 'COCKER SPANIEL'.
'for' is the link.
(Other definitions for cocker spaniel that I've seen before include "Ponies crackle (anag) - dog" , "Breed of gun dog" , "Small dog used in game shooting" , "Breed of small dog" , "Mutt" .)
