An Oregon woman was busted by cops after she punched her boyfriend in the face — twice — while the two were arguing about her dog, police said.

The suspect, 38-year-old Melissa Sue Morris, allegedly socked her boyfriend twice in the face on New Year’s Eve at about 6:15 p.m. at their home in Myrtle Point.

Morris punched him because he left her dog outside in the rain, the boyfriend later told cops.

Officers who responded to the scene noticed a marble-sized welt and a scratch on his face.

Morris was arrested on a domestic assault charge.
