When we had Alfie, he was already trained to come to the sound of the whistle. (We had him when he was 16 weeks old)
We still use this method, and he reacts straight away every time.
How do we actualy train Scoobie to react. Will he learn from Alfie, in as much that when I whistle and Alfie comes, if Scoobie comes and I reward him is this sufficiant,
