Yesterday we picked up our one year old Lab rescue dog. He was beautifully behaved during the day and settled in really well. We put him in his crate while we ate during the day and he was fine. At bedtime we put him in his crate in the living room and all went upstairs to bed. After a while he started barking. For a while we ignored it hoping he would stop but then we started worrying he would wake the neighbours and children. We ended up taking turns periodically going down and sleeping on the sofa next to him and then he seemed to be happy. So I guess this is a separation anxiety problem? Any suggestions on how we get around this? Or do we just need to persevere?
