This is a new dog muzzle.  I have included a picture  of a sizing chart to see if it would fit your doggy.  Plus I have a picture  of measurement at top of snout like chart calls for its 4.5" from.pad to inner metal wire and about 12" circumference.  So please check measurements take sure it would fit . Plus you are supposed to leave some room for then to pant and stuff so keep that in mind.
