Shadowing is normal. Yorkies are very social animals and like activity. My boys want to be near me almost always, partly for the company, but mostly so that they don't miss out on anything -- like a potential outing. They also like being close to their grandpa and have their little things with him.
If this behavior is new for your boy, I would rule out a potential health problem, just to be safe. Max got really clingy but was otherwise normal (eating and active) when I discovered he had an eye ulcer.
