Good job on the rescue dogs, @bikeboy52 !
We have three rescue dogs ourselves. I listen in a room all by myself, and I no longer listen at ear-bleed levels, but quite often when I am finishing up I find two of my dogs have parked them self quite near the listening room door. But for your purposes, if the dogs have some place else in the house that they can relocate themselves to if they find levels objectionable, that's what I'd shoot for. Back in the '90s, when I did frequently listen at ear-bleed levels and my system was in the living room as opposed to its own room, we used to have rescue cats, they would just find a place to disappear to when it got too loud for them.
