Hi, I have a 12 week old Labrador called Luna, she is potty trained and knows a few tricks an is most of the time good, one big problem is when I leave the room she will whine an scratch the door, she only does it for me, not my mum or my girlfriend, she also follows me around all the time, I work a lot so I’m not with her all the time but my mum is so I don’t understand why she whines and follows me, when it’s my mum I’m alone with her she will be calm and go asleep, she is never calm for me
