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

'come round' is the definition.
'occur' can be an answer for 'come' (thesaurus). I'm not certain of the 'round' bit.

'occasionally force dog' is the wordplay.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
'dog' becomes 'cur' (a cur is an aggressive or scruffy dog).
The alternating letters of 'force' are 'oc'.
'oc'+'cur'='OCCUR'

'to' acts as a link.

Can you help me to learn more?
