I have an almost three year old Labrador of the energetic working style. She is reasonably well trained but I now need to lift her training so that I have 'total recall' and better control over her excitement about meeting dogs or people on the street. I have read both the Labrador Handbook and Total Recall and wish I had read them when my dog was a puppy as they are far more useful than the generic dog training book I bought. So I am following Pippa's advice on starting again with the recall, having bought a harness and a long lead and a whistle. I have begun with teaching her to put her nose in my hand with a clicker marker. But I am wondering if I should adopt the whistle recall sound at the same time as I am teaching her using a clicker. I need to work with her in big open spaces where she is obsessed with retrieving (several balls and a stick at once is her preference) for which i am planning to use the whistle and long lead. But I also want to just do more training around home and when out walking so that I can eventually feel I could walk around my neighbourhood without using a lead. So my question is whether I should work on clicker for quite a while first to get her to respond to the downward hand, and only then move to the long lead whistle training for the park.
