She told police Birchmier was on top of her choking her a second time when he “commanded his pit bull to attack her by saying ‘Butter, get her!'” according to the probable cause affidavit.
After the dog bit her, the woman ran out of the residence and flagged down a passing motorist, who drove her to a location where she was met by police and paramedics.
Birchmier also was hospitalized after Butter bit him, police reported.
Butter is under quarantine for 10 days, a police spokeswoman said Friday.
A judge will determine after meeting with the city's animal welfare director whether the dog is a threat to the community and should be euthanized, the spokeswoman said.
Birchmier denied assaulting the woman or telling the dog to bite her, telling an Edmond police detective “it just got excited because we were fighting,” according to the affidavit.
He said he was only trying to keep the woman “from hurting herself” because “she was unstable” and wouldn't stop “punching herself,” the detective wrote in the affidavit.
