Spinner follows winners at Crufts (3,4)

I believe the answer is:

top dogs

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

'winners at crufts' is the definition.
I can't judge whether this defines the answer.

'spinner follows' is the wordplay.
'spinner' becomes 'top' (a spinning top).
'follows' becomes 'dogs' (dog can mean to follow).
'top'+'dogs'='TOP DOGS'

Can you help me to learn more?

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