i personally wouldnt nitpick too much about the head drop at the beginning on a 5 month pup. the pup probably isnt completely comfortable with its body yet and just wants to see where its walking before giving focus.
with more training the dog will be more confident and trust you more and not worry that you'll walk her straight into a pole.
I believe in doing it right the first time, so you don't have to go back and fix it with compulsion later. A lot don't care, start out with luring, fix little things with compulsion, etc...I just like the perfect picture from the get go. Dog learns position and not to drop it's head right away. Then I don't have to fight a mature dog every first step, for a head dropping, possibly creating conflict in the first step. A puppy who has a foundation of 100% focus in sit before we move forward at all, won't drop that head. Anyway, just my thoughts. There are many ways to skin a cat.
Edit: I should add, the only reason I noticed is because I've had to "fix" it on one dog later on. It isn't necessarily because of not trusting the handler, it just becomes a habit to drop the head. Habits have to be broken somehow, in my case and with a couple others, it doesn't just "go away." It's incredible how quickly a dog creates a little habit like that. My first GSD looked at the ground every time I rewarded it because I dropped food TWICE and let him get it. So he just got into the habit of checking for food every.single.time I rewarded. It only took one session to create the problem, and a few to break it (by blocking/popping with the leash). I should have never created the habit, so I didn't have to correct for it later.
