gspsplease suggestion is very good, I have big dogs that were doing the same thing. Positive commands, sitting, stay, down, will correct the problem, but another thing you must do is control your energy. I used to show an excited energy when I came home because I am happy to see my dogs, but the more happy I am the more excited they get. Same thing with other people, if I act happy or excited to see someone they go nuts jumping and whinning, but if I stay quiet and calm they are much more managable. My 5 big dogs are 3 labs and 2 goldens!
