"At first it was funny, but now it is a PITA."
If I had a nickel for everytime I've heard this statement I'd be rich beyond my wildest dreams!
Since you have allowed this behavior over time, it will take time and effort to extinguish. If it were me, I'd start by using a negative marker, no or eh eh, then put the puppy in another room or his crate. If he hollers ignore it, or if that isn't sufficient cover it or move it to another room. I would also work on impulse control types of things, like waiting to go out a door, holding a sit or down with some distraction, or waiting for release to get a visible treat. As others suggested, as he progresses, before he gets out of hand excited, put him in a down stay or place while you do a single short cleaning task, then incrementally ramp up from there. The behavior didn't develop overnight. It was cute and allowed for some time. Likewise, you can't expect to extinguish it overnight either, but it will end if you consistently dissuade it.
