Police say the unfortunate man had been duck hunting when the accident happened as he exited a boat.
While he did this his pooch stood on a 12-guage gun shotgun and fired the weapon, directly at the man.
This unloaded 27 pellets of birdshot into his bottom and left him needing to be taken to hospital to have them removed.
However, docs say he'd been lucky -- if he hadn't been wearing his waders, he would have been seriously injured.
