Snow vehicle follows cliff path, perhaps (3,6)

I believe the answer is:

dog sledge

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

'snow vehicle' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'follows cliff path perhaps' is the wordplay.
'follows' becomes 'dogs' (dog can mean to follow).
'cliff path perhaps' becomes 'ledge' (ledge around a cliff).
'dogs'+'ledge'='DOG SLEDGE'

Can you help me to learn more?

I've seen this clue in The Times.
