Well Molly at 2 years and 3 months is not exactly an old dog, but most people seem to clicker from a much earlier age. I tried clicker training when Molly was younger, but I got nowhere with it. I had read Karen Pryor's book. I don't know if it was my ineptitude or the fact that she is a VERY lively dog, but it just didn't work for us despite several attempts on my part. Fast forward to this (oops, sorry last ) year and her lead walking was worse than ever. She was hugely distracted by smells (dog wee) and all the food, apples, blackberries etc raining down from above. Our walks became a seris of lunges, with periods of me standing stock still so she couldn't move. It took forever to get anywhere, because I was trying and failing to deal with her poor behaviour and I began to regard walks as a wrestling match. In late Autumn I decided to give the clicker one last go before calling in a Trainer/Behaviourist. Our first success came with her leaving luscious smells when told to. It didn't take her too long to figure out that if she left when told to a click and treat would follow. Our course became a little straighter as there was less zooming from side to side in a seris of lurches. She then realised that if the lead was slack, a click followed by a treat appeared. Everytime she was in the zone I clicked and treated. I was practically force feeding the poor dog, I must have sounded like a demented typewriter. Her lead walking is so much better now. I can accomplish our walks in a reasonable period of time. The C& T is naturally fading, but every now and then I do an intensive C&T for a short period, just to keep her interested. I am now getting fussy. I read a little about shaping and decided that I want her shoulder by my knee when we are walking. So now I only click when she in exactly in position. She is getting the message very rapidly.
