Sorry to hijack the thread, but my puppy Bison has also just started walking around the block (finally got him to stop chewing on the lead, or hitting the ground)
Although he isn't distracted by people too much and tends to follow me, run when i run etc, he stops to smell a lot of things. sometimes he will smell something for so long that it annoys me and i say "lets go" he knows this means go yet he will persist to smell the said thing in question. I know this is natural dog behaviour, but how can i make him more focused on walking and less focused on the things to smell.
