I have an 8 month old Border Collie. We've had Dahli since she was 9 weeks old. And of course the day we brought her home and on she did all of the puppy things. But they were just getting better... the problems were starting to go away. But now they are slowly coming back. I don't know what to do. How do you train a Puppy that already knows it's bad?? Please help if you can!!
It is like the terrible twos. just becuase you trained them once doesn't mean they listen. Esp working and herding breeds, they can test every nerve in your body. Start all over again. Reinforce what you think she already knows. It will come around in time, but you have to be consistant and continue training, just like you would a child.
