Talk about a name for a dog (7)
I believe the answer is:
spaniel
'a dog' is the definition.
(spaniel is a kind of dog)
'talk about a name for' is the wordplay.
'talk' becomes 'spiel' (spieling is a kind of talking**).
'about' means one lot of letters goes inside another.
'name for' becomes 'n' (I've seen this in other clues).
'a'+'n'='an'
'spiel' enclosing 'an' is 'SPANIEL'.
(Other definitions for spaniel that I've seen before include "Alpines (anag)" , "Gundog; obsequious type" , "[HOUND]" , "Springer- - -" , "Droopy-ear dog" .)
