Agrees it's not for dogs (7)

I believe the answer is:

concurs

'agrees' is the definition.
('concur' can be a synonym of 'agree')

'not for dogs' is the wordplay.
'not' becomes 'con' (I've seen this in other clues).
'for' says to put letters next to each other.
'dogs' becomes 'curs' (cur can mean a violent dog).
'con'+'curs'='CONCURS'

'it's' is the link.

I've seen this clue in the Evening Standard.
