So far, when our puppy plants her little feet and refuses to go, a slight tug on the leash and the word "come' will make her start again - when she is just too distracted by noises, birds, cars, bicycles, people walking by, leaves blowing, strong winds, etc. ( in other words everything) it is sometimes a constant tug, walk, come, tug, walk, come, tug, walk, come, but try as she may to refuse, we just keep on walking, and she has to follow - if I had to pick her up we'd all be in big trouble, because I don't see me carrying her on my shoulders, ever.
