My dog likes sitting by my speakers. Like right next to them and he looks at me when I turn off my system. I can be cranking dubstep metering at 110db and he is very content. Same in my truck. He bothers me when I don't have music playing but will lay down in the backseat and go to sleep if the music is playing. Strange? I think so. I know he does not care for classical or anything that is soft playing. But as soon as I play something with a beat he comes out of my home office and lays in the living room. He loves bass and I think it's pretty cool.
Nope, my dog leaves the room when the volume gets loud. However, at normal volumes, he seems content to listen with us. Plus, it is always funny when a scene with barking/howling dogs comes on -- he'll pop his head out from under a blanket or lift it from our laps and his ears perk up and just tune in as he stares at the speakers and tilts his head, like "but...those aren't dogs" lol.
No problems except on some loud explosions or thunderclaps (my dog is afraid of thunder). My dog used to leave the room when I practiced my trumpet, but now she just lies there. I'd like to think I was getting better but she's probably just getting old...
