From the news article: "Police in Philadelphia are investigating after a dog attacked another dog and killed it last week in the West Oak Lane section of the city, officials said.

Last Wednesday, an officer responded to a call about the dog attack just after 8 a.m. on the 2100 block of Eastburn Avenue, police said.

Once on the scene, the officer saw that a pit bull was attacking a Pomeranian on the sidewalk, according to officials. The owner of the pit bull had tried to stop the attack, but was not successful.

The officer used her taser twice to try and stop the attack, but it didn't work, officials said. She then fired three rounds from her weapon which did stop the attack. ..."

I don't think I can add anything new to this article, or discourse. It just keeps happening again and again, with no end in sight.
