Restraint for a retriever (5)

I believe the answer is:

leash

(Other definitions for leash that I've seen before include "Rope to control dog" , "A dog walker may use it" , "Spanish city famous for swordmaking" , "Line for holding dog" , "Animal restraint" .)

I've seen this clue in The Wall Street Journal.
