Two neighbours in the US state of Mississippi drew weapons and fired at each other as an argument over a defecating dog ran out of control.
Associated Press news agency said Jerry Blasingame, 60, has been charged with assault for shooting Terry Tehnet, 52, with a shotgun.
Mr Tehnet was angry because he thought Mr Blasingame's dog had defecated on his lawn, in a rural part of the state.
Mr Tehnet, whose injuries are not life-threatening, may also be charged.
The two men gave AP different versions of what happened.
'Meet me at the levee'
Mr Tehnet said he visited his neighbour to complain about dog "poop" on his property.
Mr Blasingame blamed him for shooting his dog the week before, Mr Tehnet said, and told him: "Just meet me at the levee and I'll shoot you down."
Mr Blasingame told AP he got his gun and drove off but Mr Tehnet did not follow so he returned to the neighbourhood.
The two men confronted one another again and 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, AP reported.
Washington County 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."
Didn't think it would copy properly because of the picture.
