I am currently working way through this with my 14 month old lab. We are doing it to the letter but my lab is bloody greedy it is hard to wait for her to be distracted in the house to practise because she follows me around knowing treats are likely. She hears me pick up the whistle even!
Has anyone done this method and did you stick religiously to it especially the first bit? I am wondering whether to skip forward but don't want to wreck it. My lab seems to clearly understand whistle means food.
