Hi again,
We started clicker training with our now 5-month old whippet cross, Millie, before Christmas and have been going weekly. Doing fairly well, though puppy goes hyper in class with all the distractions! Whereas she used to sit really quite well and obediently with hand and/or voice command several weeks ago (for a treat), she is now refusing to sit at all without one. Instead of sitting, when I give the command (voice or hand) she just wanders off completely disinterested. She is a bit better at home (where there are fewer distractions) with the sit, but not as good as before. I think it seemed to start after we began with the sit and stay command (she was sitting well when we progressed to this).
Now, the trainer says I should have started to phase out the treats earlier on in the training, but I have to say, I did not do this (since at the time, I didn't realise I had to - maybe I missed the instruction in class at the time - too distracted trying to keep Millie under control!!). So I'm wondering what to do now? She's a very food-oriented pup and very bright and energetic. Do I go back to square one, clicking and treating each time for the sit, then starting to phase out? And leave sit and stay for a while? I feel a bit confused about this! Maybe it's a rebellious phase she's going through... would this happen at 5 months?

Also, at 5 months, I'd be really interested to know what sort of level of training can be reached with the clicker, since the pup is still very young, really? Maybe my expectations are too high - not sure!!
Thanks everyone for your input!
