My dog had a "thing" about moving bikes which wasn't totally unexpected, she loves to chase and is so fast and can be there one minute and gone the next

before you have time to realise.
Anyway, I took her to plentyu of places where there were cycle paths (and of course when you plan a session do any bikes turn up? NO!!!!) This was the previous winter so she must have been around 8 - 10 months in age.
I started by taking her on normal collar and lead to where bikes would go past, so she could see them and get used to them, but not so close that she reacted. If she did react, I moved slightly further from the path. I was aiming for interest but not obsessive reaction :)
I use a clicker and she already knew it marked the correct behaviour, so when she did behave well, such as just looking at a bike, I clicked and treated after the bike had gone past. (the treat was either cheese or a tug with her toy :) ). After a while when a bike came she would look at me and get the click and treat, and graduallyover weeks I moved her closer and closer to the bikes as they went past.
As far as I know she is now totally fine around them, but if I see either a bike or a jogger esp a fast one i do call her to me and get her to sit and wait til theygo by, i feel this helps to improve public opinion of dogs and owners generally.
I did try using my other half on a bike to assist with the training, but gave up very quickly as she got so excited seeing "dad" on his bike, she was totallyOTT and too silly to train, but i expect it is a very good idea if the dog doesnt go "bonkers" at the time ;) :p
