Current shedding machine that barks and digs holes and howls at the dog satellite is a fraidy cat about guns.. but don't you go near his yard. He's a baying machine. Beagles are like that. He doesn't liek the noise guns make, slide racking etc. he's also nervous about bubble wrap.
I had a dog when i was a kid that we took shooting/camping all the time, she ran off/got lost once, when she came home she was terrified of guns. We think someone shot at her or shot her with a bb gun.. can't think of any other reason, as she was the kind of dog that loved the outdoors.
Also had a PRO gun dog. A springer named Bear.. if you picked up a gun case he literally would shake with anticipation... cuz that mean we were going hunting! He would get terribly depressed when we'd leave him at home and hunt elk for ten days. He even liked handguns! You'd get out the guns, even just to clean them and he'd sit by the door, eyeing us, like hey.. are we going? Then again i used to run him in a big drainage with a training dummy launcher /and or pheasent wing-covered baseball glove and starter pistol since he was a wee pup. He got used to the idea that BANG meant.. find that bird! (And he got the liver) He'd run ahead, turn around and chuff at you when there were no birds nbearby, but if birds were "in range" he'd stay inside your field of fire. He'd also sit still while we watched elk fight it out. He'd even come outside for fireworks. He was the BEST dog I ever had..
Get all misty eyed when I write about him.
