LOL! Rocco not only had the zoomies, he would be the most obnoxious, fresh little trouble maker at night, after being an absolute angel all day (he would even pee on the floor right in front of me!!). We used to call him the "Vampire Puppy", because he would get so crazy once the sun went down!
But rest assured, he grew out of it at about 5 months...now he just wants to play fetch incessantly until 10:00pm!!
