doggo

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

'keeping low profile' is the definition.
I can't tell whether this definition defines the answer.

'harry quit' is the wordplay.
'harry' becomes 'dog' (I've seen this in other clues).
'quit' becomes 'go' (I am not sure about this - if you are sure you should believe this answer much more).
'dog'+'go'='DOGGO'

Can you help me to learn more?

(Other definitions for doggo that I've seen before include "lying to avoid detection!" , "(Lie) silent and in hiding" , "Quiet and hidden" , "How some people lie!" , "(Lie) concealed" .)

I've seen this clue in The Times.
