Boxer dog? (3)
I believe the answer is:
pug
I believe this is a double definition.
'boxer' is the first definition.
(short for pugilist - term for boxer)
'dog' is the second definition.
(I know that pug is a type of dog)
(Other definitions for pug that I've seen before include "Small compact dog" , "Small dog with flat nose and wrinkled face" , "Dog breed; worked clay" , "Dwarf breed of bulldog" , "This nose is like a boxer's" .)
