Seized like a dog (8)
I believe the answer is:
collared
'seized' is the definition.
(collaring is a kind of seizing)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for collared that I've seen before include "Caught - variety of dove" , "Grabbed; type of dove" , "like some doves and peccaries" , "Seized" , "like certain doves" .)
