Insecure, unloved dog? (3)

Ross

I believe the answer is:

cur

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

This clue could be a double definition.

'insecure' is the first definition.
(in the letters 'seCURe')

'unloved dog?' is the second definition.
'cur' can be an answer for 'dog?' (both can mean a despicable person). I'm not sure about the 'unloved' bit.

Can you help me to learn more?

(Other definitions for cur that I've seen before include "Mongrel - coward" , "A low worthless dog" , "Aggressive dog" , "Surly dog (or person)" , "Vile dog" .)

I've seen this clue in the Evening Standard.
