Hello, I am new to this forum and the owner of a 4 month old Male yellow lab. I got him at 7 weeks old and have been working with him daily. He has been doing well with the sit and stay command. The Here command is pretty good unless he has something in his mouth. From the very beginning in the hallway he would fetch the puppy bumper but would be hit or miss on returning to me. I did not worry about it at the time. Only 3 retrieves per day. As he got bigger we moved outside and in a confined area he still runs away with the bumper or does not return to me. I have searched the forums and the common thread is to stop retrieving and work on Obedience. So I am doing that. I have put a check cord on him to reel him in. The issue I am having, is when the check cord is on he wants to chew and play with it causing a "tug of war" when I reel him in on the command. Is this a problem and if so does anyone have any suggestions. I just started this process yesterday. This is the first time I have been serious about training my dog. I have had one other lab that I started but life and work caused me to not finish her. She did not have this problem so I am unsure how to deal with this problem. FYI I have been following the Wildrose Way training DVD. Any and all suggestions are welcome.
