Just to let you know we couldn’t get hold of the whistle but bought a clicker instead. Waited until it was quiet, read all the information and started with getting her to sit. Even though she could do this by voice I wanted to start all over again so she understood it with the clicker. She got this straight away. Moved on to getting her to lie down, and after a couple of minutes she got what she had to do. I stuck to these two last night and when I stopped she followed around my feet!!! I am amazed at how quick she has taken to the clicker. Looking forward to trying some more tonight. Thanks for the advice.
Tried it with my other dog so she didn’t feel left out and it took alot longer for her to Lie down, but she got there in the end. 😛
