pekes

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

'dogs' is the definition.
(Peke is an example)

'head of police has possibly to seek?' is the wordplay.
'head of police has' becomes 'p' (I can't explain this - if you can you should believe this answer much more).
'possibly' indicates an anagram.
'seek' with letters rearranged gives 'ekes'.
'p'+'ekes'='PEKES'

'the' acts as a link.
