I have a 3 y.o Australian Shepherd (23 inches tall) & he is used to walk on heel on my left, I wanna teach him how to run next to my bike on my right. He has never tried (even once) biking so am trying to teach him on a slow speed but he always tries to walk in front of the bike or crosses my way to go to my left (when he does he is pulling). Am also afraid that he might pull me whenever he sees something interesting on the street (although he is not into hunting birds, bunnies & the like). How can I make him identify that on the left is the "walking" and the right is the "biking". I go to work with my bike almost everyday and it would be more fun for me and my dog to go biking together, the only question is "how?" am so clueless how to even get started. Please advice ^_*
