My 3 month old pup is not doing great in training. I have training sessions with her daily, but she doesn't see, to catch on. I make the training sessions fun, with treats and praise, but she ignores praise and greedily lunges for any treats. I never hit her or abuse her or force her into doing something, and she never had a former owner who did that either. I'm consistent in commands, i never change them, and I use hand signals too. She doesn't seem to be very focused when we are training. I'm trying to teach her sit, down, stand, and come. Sit is pretty good, but she doesn't usually obey immediately and half of the time she lays down when I tell her to sit. I know not to repeat commands, so I'm not sure what is wrong. She usually ignores the command down. She knows come very well, but she also knows that when she doesn't have a leash on, there is no way I can make her come. She also ignores the command stand. Any advice on what I could be doing wrong?
