What can we do about my dad's dog?

So he got this dog 2 year's ago from some guy he knows because he felt bad that he kept her in a crate all the time. Well here is the thing she constantly whining non stop unless you're petting her and even then she starts whining a little bit and is trying to get on top of you she just permanently reacts like you just came home from a week vacation. What is something I can recommend my dad to make the behavior stop
