When you right-click a horse and select "Giddyup," you move towards the horse and get onto it. Leading another animal would be essentially the same. Right-clicking the animal and selecting "Lead on" would cause you to run over to it and grab it by the scruff of its neck (maybe a new bridle item or the suggested shepherd's crook would have to be in your hand?), letting you move yourself and the animal more precisely.
When I originally posted this thread it was right after spending a good 10 minutes trying to wrangle a few escaped sheep back into their crowded pen using only "shoo" and some rope for leashing. It wasn't fun and I kept wishing I could just move them around like you can move horses.
Edit: I guess it's pretty hard or even impossible to lead an animal like a pig, sheep or cow in this manner. Maybe that's what jorb meant with his response. Halters, however, are a common piece of equipment. Often an animal must be "halter-broken," but this might be unnecessarily complicated. A halter item which you apply to an animal would allow you to lead the animal as described.
