New to the board and reading it you guys are wonderful, so I am looking for advice. I have a 11 1/2 yr old female GSD Ruby, a 5 yr old male GSD Bear, and a 1 1/2 yr old male GSD Riley. All three of them are altered. The problems are coming since Riley is maturing and trying to find his place. I get that part. What I don't get is that as Ruby is getting older, and her sight is not the best anymore....she is now being attacked by Bear also. She has been pretty much Dominant until recently. Ruby came to us over 9 years ago. Bear has been here since 10 weeks old, and Riley since 8 weeks old. She has been motherly to them, with the occasional bark and nip to drop them in line. They sleep on the floor surrounding my bed. Ruby has to pass by Bear to get to her spot. Over the last couple of days Bear has been growling at her when she passes him to lay down. At NO OTHER TIME. Just when she tries to lay down. Yesterday he growled and she attacked him! When Ruby attacked Bear, Riley attack Bear from the other side! This went on for 5 minutes as I called the Leave it commands and No and stop. They did not hurt each other. Maybe a little pride. Is Bear trying to take dominance from her because she is aging? Has anyone else had this problem? I am starting to apply their training again as I got lax in it. I now am reapplying the sit stay to feed, and the sit stay to go through doorways. Any help would be appreciated before one of them gets hurt. Also is it wise to have two or three males together?
