Nelson probably sleeps about 8 hours or so at night...give or take. He goes to bed whenever my mom does, and then gets up whenever she does. So it depends on the day.
And then throughout the day he takes like cat naps. He is always getting up and walking around. Like if we leave the room he gets up to follow us sometimes. Other times he stays zonked out. And while we are out I'm not sure what he does. I will have to video tape him again. When we first started locking him in the kitchen when we go out instead of his crate (which he barked in)...he walked around, barked, howled, laid down, got up, walking around barked, howled, cried....so I dunno if he still does that now. I hope he naps for a couple hours!
