Get to see about a dog (6)
I believe the answer is:
secure
'get' is the definition.
(securing is a kind of getting)
'see about a dog' is the wordplay.
'about' is an insertion indicator.
'a dog' becomes 'cur' (a cur is an aggressive or scruffy dog).
'see' enclosing 'cur' is 'SECURE'.
'to' is the link.
(Other definitions for secure that I've seen before include "Safe against attack or intrusion" , "Free from danger and financially sound" , "Make safe or fasten" , "Safe, protected" , "land" .)
