Hi, we have a 5 year old Coker spaniel who is great but gets very anxious when left alone. Licking his paws, drooling scratching at the front door and of course barking. He is very attached to my husband and can whimper if anyone else in the house gets near him and he will try to jump in between the person and my husband. My husband is keen to get another dog to help with the anxiety when left alone but I am not sure it will help and I am also concerned at possible jealously issues. Does anyone have any experience with this, does getting a second dog help?
