Way one stops little (Scottie) dog (6)

'dog' is the definition.
(breed of dog)

'way one stops little scottie' is the wordplay.
I cannot really understand how this works, but
'way' could be 'st' (abbreviation for street) and 'st' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
'little' could be 'wee' (similar in meaning) and 'wee' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
