I have an almost 4 year old golden, she is my avatar, and I have a spray bottle with water and instruct down or stop. If she doesn't I spray her with H2O. If she is out of control and excited now all I have to do is pick up the bottle and she quickly retreats. It doesn't hurt them and for some reason dogs do not like being sprayed in the face. Lots of luck. She is just now quieting down, we rescued her when she was 1 1/2 and she really must not had any discipline because she doesn't think she does anything wrong. I wouldn't trade her for anything. Great dogs.
