I just noticed this today.... My dog either has a strange reverence or fear of guitars. He has an obsession with fetch and return of the ball, normally I do not allow the ball inside the house because if it rolls under a sofa or cabinet he will make short work of it in trying to get to the ball, he would chew through a 4x4 to get to his ball. Not pretty. today a mistake was made and the ball was allowed inside the house, though luckily it didn't roll under any furniture .... instead it rolled up against an acoustic guitar that was leaning up against the wall. It was brought to my attention when working outside, I heard the dog barking Non- stop and loud.... I go in the house and the ball is sitting right there for the taking, just touching the guitar but he wont get it with even his paw... ( mind you, this is the dog who knows how to open the sliding glass door) but he's sitting back 3 feet away mesmerized and barking. I tested it out and sure enough, when I move the guitar towards him he backs away... course, it could be just his way of telling me I've been playing out of key.. Any one else have pets with strange behavior?
