Animals and audiophiles

Lately a few members have mentioned their pets and posted pictures of them in addition to their systems. Its brought to mind this feeling of guilt Ive had the past few years concerning our two rescue dogs. These animals like so many rescues live to be around us at all times following either my wife or I from room to room. My schedule is to return home from work in the afternoon and preform my doctor ordered exercises while listening to music every week day..This can be from one to two hours depending on how focused I am and of course the dogs have been alone at home all day and want to hang out. So you can  see the dilemma Im sure, like most bommers I listen to mixture of rock, jazz and blues and sometimes you just want to crank it up a little especially while exercising. Never been a headphone guy and really don’t want to start digging a new money pit either. Its said that they can hear up to 35khz I know but its the levels that concern me, most days I may bump up the volume a little but within a few minutes the guilt kicks in and I turn it back down, shutting them in another room is not a great option and I can’t put them outside because we have Coyote problems in our neighborhood. I’ve read that they can shut down their inner ears to block out background noise so they can focus on particular sounds and wonder if that’s so, they never show any signs of discomfort ,drives me crazy when they’re laying on the floor right in front of a speaker. Any audiophile vets out there care to weigh in? Thanks in advance! Oh and please don’t forward this to PETA Im doing my best.
