Runs inside to take care of dogs, leaders of the pack? (12)
I believe the answer is:
trendsetters
'leaders of the pack?' is the definition.
'trendsetters' can be an answer for 'leaders' (I have seen 'leaders of fashion' mean 'trendsetters' so perhaps 'leaders' could also mean 'trendsetters'). I am unsure of the 'of the pack?' bit.
'runs inside to take care of dogs' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'inside' means one lot of letters goes inside another.
'to take care' becomes 'tend' (I've seen this in another clue).
'of dogs' becomes 'setters' (I can't explain this - if you can you should believe this answer much more).
'r' put into 'tend' is 'trend'.
'trend'+'setters'='TRENDSETTERS'
Can you help me to learn more?
(Other definitions for trendsetters that I've seen before include "leaders of fashion" , "Many may follow their lead" , "People who are in" .)
