In the last couple of month, mostly over winter, my dog has been very Dominant over everything. It didn't bother me much at the beginning but now he becoming Dominant over me.He a very well train dog he listen to everything I say. I been doing a lot of stuff with him like walking every day, taking him out side and playing with him, but once he get in the house it starts all over again. I even try not letting him up on the bed or the couch without being call up. Like the other day my step dad and I was playing and he just start jumping up and biting at both of us. in the car its even worse. People walk by the car and he goes crazy. I can't even keep the window in the back down a little because he will start to push the window down. He is a Lab/Chow and just turn 4 in march..
