I have been running the vacuum and letting him bark instead of putting him outside. I figure next is correcting the barking but truthfully I dont have that licked yet except for water bottle. He thinks there is something evil in it I guess. He loves water.
I don't think the fact he was born in a barn has anything to do with him hating electronics. All puppies are scared of vacuums, clippers, blow dryers. You just have to train them that they are not going to get hurt and they need to let humans do what they need to do to help them. Like cutting their nails.
I start when they are tiny puppies bathing and blow drying them. Running them vacuum around their pen.
