Just not Getting it.
Good morning to all! I'm new to the forum and I have a three year old Pit Bull named Star and she's a very good dog. I have trained her with consistency, but it seems she just doesn't get it. Before I let her out of her crate, I make her sit-stay so that she doesn't just burst out of the cage out of control. I can't understand why I have to do this every time I get ready to let her out. When I tell her to lie down, she lies on her stomach and inches forward, and if I leave the room, she gets up. I need any tips on how to get my dog to be more obedient to the commands that I know that she knows. I don't exercise her like I should. When is the best times to train? How can I get her to catch on to the daily routine? She's also aggressive towards anything unknown.
