Today's dumbass learned a gun safety 101 rule. Don't leave a loaded shotgun in the back of your truck with the safety off. That's what a 46-year-old man named Richard in Wyoming did...and then his dog jumped in the bed of the truck and stepped on his rifle. The gun went off and Richard's dog ended up shooting him in the arm. Luckily, his injuries were not life threatening....and that'll teach him to neuter his next dog.
