So I have a lovely rescue for the last three months and am building up to leaving him on his own for short periods. I have camera that allows me to see part of the room when I’m not there but due to the shape of the room and furniture I can’t always see him. I was wondering if there is a recording device that would let me know if he barked or became distressed. I don’t really want to listen to the full time if he silent. Just want to know when he’s not. Does such a thing exist or am I going about it wrong. Thanks
