Breed of sheep daughter kept in her Highland town (8)

I believe the answer is:

herdwick

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

'breed of sheep' is the definition.
The definition suggests a singular noun which matches the answer.

'daughter kept in her highland town' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'kept in' means one lot of letters goes inside another.
'highland town' becomes 'wick' (I've seen this before).
'her'+'wick'='herwick'
'd' going within 'herwick' is 'HERDWICK'.

Can you help me to learn more?

(Another definition for herdwick that I've seen is " Cumbrian breed of sheep".)

I've seen this clue in The Times.
