Follows advanced winter transport (7)

I believe the answer is:

dogsled

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

'transport' is the definition.
(dogsled is a kind of transport)

'follows advanced winter' is the wordplay.
'follows' becomes 'dogs' (dog can mean to follow).
'advanced winter' becomes 'led' (I can't explain this - if you can you should give a lot more credence to this answer).
'dogs'+'led'='DOGSLED'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
