Snub-nosed dog
I believe the answer is:
pug
'snub-nosed dog' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pug that I've seen before include "This nose is like a boxer's" , "Small dog with flat nose and wrinkled face" , "Small stocky dog" , "Dog with broad flat nose, or short fighter" , "Flat-nosed dog breed" .)
