Sleepy puppy

I’m a first time puppy owner , I have a miniature dachshund who is 4 months old, I’ve had him 9 days.

i was just wondering how normal it is for him to be sleeping so much!
I swear he’d sleep all day if I stayed there, lol.
he’s right now going into a 2 hour nap.

food doesn’t even rouse him.
In the mornings I have to physically pick him out of his crate to go potty lol
