'reward for going' is the definition.
'golden handshake' can be an answer for 'reward' (I've seen this before). I'm unsure of the 'for going' bit.

'kennel has had dog barking' is the wordplay.
'barking' is an anagram indicator ('barking' can informally mean mad).
'kennel'+'has'+'had'+'dog'='kennelhashaddog'
'kennelhashaddog' anagrammed gives 'GOLDEN HANDSHAKE'.

'in' acts as a link.

Can you help me to learn more?
