It has a strong scent (10)
I believe the answer is:
bloodhound
'it has a strong scent' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for bloodhound that I've seen before include "Large tracking dog" , "Dog to follow trail" , "10 [SLEUTH]" .)
