Authorities said 36-year-old April Martin moved out of her home located at 1931 N.W. 30th Street in Oklahoma City in November.
The man, Marvin Derrell Brown Jr, was removed from the home and Martin reportedly moved out as well.
The medium-sized pit bull was covered in urine and feces as well.
The animal appeared skeletal to authorities. The necropsy reported the official cause of death was starvation/dehydration.
One count of animal cruelty was filed against Martin on Friday in Oklahoma County.
