Deal with it harshly being dogged (6)
I believe the answer is:
tailed
'being dogged' is the definition.
(I've seen this before)
'deal with it harshly' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
The remaining letters 'ailed' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tailed that I've seen before include "Dogged" , "Followed, tracked" , "Secretly followed" , "Followed like rear appendage" , "Followed informally in detail" .)
