Former print worker, kind towards dog (10)
I believe the answer is:
typesetter
'former print worker' is the definition.
(historical type of print worker)
'kind towards dog' is the wordplay.
'kind' becomes 'type' (type is a kind of kind).
'towards' is a charade indicator (letters next to each other) (I've seen this in other clues).
'dog' becomes 'setter' (setter is a type of dog).
'type'+'setter'='TYPESETTER'
(Other definitions for typesetter that I've seen before include "Compositor" , "Press worker" , "One doing composition" , "Former newspaper employee" , "Printing expert" .)
