We still alternate our training sessions between 2 x 2's and dog walk. I'm pretty happy with how quickly she's progressed with 2 x 2's and is super close to having them straight. I tried to straighten the back ones yesterday but she hasn't quite got the hang of finding the entry when they are straight. I feel confident that after another few sessions we'll get there. I also need to start doing some sessions away from home to generalise the behaviour.
