Follows very kind horse around boutique (4,5)

'follows' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their -s form.
Perhaps you can see an association between them that I can't see?

'kind horse around boutique' is the wordplay.
I cannot quite understand how this works, but
'horse' could be 'long' (long horse is a kind of horse) and 'long' is found in the answer.
This explanation may well be incorrect...

'very' is the link.

Can you help me to learn more?
