A Pittsburgh Bureau of Police officer from Zone 6 responded to the 3000 block of Ashlyn Street for reports of an unconscious male who was possibly having a seizure just before 12:25 a.m.
When he arrived on scene to provide aid to the male while EMS was en route, a Rottweiler that was running loose charged at him, biting him in the back of the thigh and knocking him to the ground. As the officer was getting back up, the dog lunged at him again.
This time the officer discharged his weapon, killing the dog. Police dispatch was informed of what had occurred.
The officer was able to then aid the victim on the sidewalk. EMS arrived and transported the male to Mercy Hospital in stable condition.
The officer was also transported to the hospital and treated for his injuries.
It was later discovered the animal belonged to the male patient.
Animal Care and Control will take possession of the deceased dog.
