I have recently moved from acreage to the city. My dog used to bark when I left but no one could hear him and my neighbour said that he stopped after I left, so it was a bit of a game. I have now adopted a stray who has separation anxiety and carries on when I go out and and my 7 year old is joining in. Do I need to do the "leave and come back quick and make it longer and longer" until they realise I am coming back. I like to leave my big dog in the house when I'm not home as I'm not in a good area. They are in the house most of the time and I am home most of the time. Should I start making them spend part of the day outside so they are not so attached to me? I also have a little blind dog but he's happy with the big dog around.
