Two neighbours drew weapons and fired at each other after an argument about dog 'poop' got out of control.
Jerry Blasingame, 60, has been charged with assault for shooting Terry Tehnet, 52, with a shotgun, reports the BBC.
Mr Tehnet was angry because he thought Mr Blasingame's dog had defecated on his lawn, in a rural part of the Mississippi.
Mr Tehnet, whose injuries are not life-threatening, may also be charged. He told police he visited his neighbour to complain about dog "poop" on his property.
The two men confronted one another with each claimed the other produced a weapon first.
"He shot twice, I returned fire," said Mr Blasingame.
Mr Tehnet said Mr Blasingame opened fire first with his shotgun so he took his pistol from his car and fired back.
He said he was hit in both hands, the shoulder, chest and side by shotgun pellets.
Chief Deputy Sheriff Billy Barber said: "Homeowners and property owners need to respect each other's property... If a dog did that in your yard, call the law. Don't take matters into your own hands."
