NASHVILLE, Tenn. (AP) — An argument that started over a dog led to a shooting that left eight people wounded in Tennessee. Nashville police said they were looking for two male suspects.

Authorities responded to reports of gunfire shortly after 1 a.m. Sunday, the Metropolitan Nashville Police Department said in a news release. None of the injuries were life-threatening.

The statement said the two suspects began arguing and one of them had a dog with him. The suspect with the dog pulled out a handgun, police said. The second suspect left, then returned a short time later with a gun and accompanied by several other men. An exchange of gunfire ensued.

Police said they recovered a handgun from the scene and that the investigation is ongoing.
