'subjected to discipline' is the definition.
I can't tell whether this definition defines the answer.

'barking spaniel my boss' is the wordplay.
'barking' is an anagram indicator ('barking' can informally mean mad).
'my boss' becomes 'ed' (abbreviation for editor, the setter's boss).
'spaniel' anagrammed gives 'penalis'.
'penalis'+'ed'='PENALISED'
