Ronnie's dog? (6)
I believe the answer is:
barker
This clue could be a double definition.
'ronnie's' is the first definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I don't see?
'dog?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for barker that I've seen before include "setter, perhaps" , "Loud showman and dog" , "Tout" , "One stands at a carnival giving loud, colourful, sales talk" .)
