We rescued our lovely lurcher four years ago and he has been a dream. He has been the most relaxed chilled out dog ever. Until a few feels ago. We can't put our finger on anything that has changed to make this happen but he is crying during the day. Even when we are here he is crying and pacing up and down. At night time he settles and crashes out but I'm not sure If this is just because he is exhausted. He is losing so much sleep as he usually sleeps all day. Has anyone experienced this with their dog please ? I really want to help hiM it's so awful seeing hiM so unhappy 🙁
