I know the theory - i.e. Pippa Mattinson Total Recall - change direction, be unpredictable, make dog keep an eye on you, hide behind trees etc, but having tried all of these consistently over the course of many weeks my dog still ranges too far from me. He has an excellent recall but that means I am having to call him every 10 seconds or so because he is constantly ranging quite a way at a pace.
I have a longline and have been keeping him on it more but none , and I mean none, of my other friends with dogs have ever even had to train this - their dogs naturally stay within 10 metres or less of them - what am I doing wrong ??? Any advice / tips ???
