Names dogs (4)
I believe the answer is:
tags
This clue is a double definition.
'names' is the first definition.
(tagging is a kind of naming)
'dogs' is the second definition.
('tag' can be a synonym of 'dog')
(Other definitions for tags that I've seen before include "trite Latin quotations" , "They are able to identify" , "Labels; quotations" .)
