Heard dog barking in Louth town (8)

I believe the answer is:

drogheda

I'm a little stuck... Click here to teach me more about this clue!

'louth town' is the definition.
'drogheda' can be an answer for 'town' (I have seen 'Irish town' mean 'drogheda' so perhaps 'town' could also mean 'drogheda'). I'm not certain of the 'louth' bit.

'heard dog barking' is the wordplay.
'barking' indicates anagramming the letters ('barking' can informally mean mad).
'heard'+'dog'='hearddog'
'hearddog' with letters rearranged gives 'DROGHEDA'.

'in' is the link.

Can you help me to learn more?

(Other definitions for drogheda that I've seen before include "Louth town, Boyne port" , "Irish port" , "somewhere in Ireland" , "Irish place" , "Irish town" .)
