Ring caught by dog to be found (5)
I believe the answer is:
occur
'be found' is the definition.
(I've seen this before)
'ring caught by dog' is the wordplay.
'ring' becomes 'o'.
'caught' becomes 'c' (cricket abbreviation).
'by' is a charade indicator (letters next to each other).
'dog' becomes 'cur' (I've seen this before).
'o'+'c'+'cur'='OCCUR'
'to' acts as a link.
(Other definitions for occur that I've seen before include "Befall" , "crop up" , "Happen - to come to mind" , "Go on" , "Happen, take place" .)
