Hi folks!!! I am searching out as much help as possible! I just adopted my first Doberman from a shelter about five days ago. We are just getting to know each other. What his papers said was that he is 1 year and 7 months old. He lived on a farm and they got rid of him because he chased the horses. He was an outside dog. (That seemed weird given that he is a short hair). He isn't potty trained, but I haven't had an issue. I guess I really don't know much for sure. Except one thing, he loves my 11 year old daughter, and he is glued to my side. I can't complain. He is a sweetie when it is just the three of us. (well five) We have two cats, however, I am not so worried about those relationships, I am sure they will grow. He is afraid of the cats, but the fear is diminishing as he realized they don't have claws. My main concern is that he is extremely aggressive with other people. My neighbors are on the other side of a six foot privacy fence, but they fear him because he barks sooooo loudly and growls. I had a guest over today that was very fearful because Harley wouldn't stop barking and growling at him. He even started pumping his back legs like a bull. The thing is, he listens to me only to a point. If I hold his collar or put a leash on him, he will stay by me, but continue this behavior. I can crate him even though he is barking, but I suspect he doesn't appreciate that and I didn't feel right about it. I would like to learn how to handle the issue. I have to be honest, I was scared and I know he could feel that. I need help with how to calm my own fears and how to help him feel safe around people other than my daughter and I. Any ideas are welcome!!! Thank you!!
