Welcome to the site, you will find this to be a very helpful tool.
To answer your question, no letting them walk out in front of you when working a long leas like a flexi, etc. Will not effect your leadership with your little buddy.
Just make sure it is because you let them walk out in front and you are still leading the way. Meaning do not let your dog drag u and decide which way to go. When you hit intersections, they should be looking back at you as to which way to go. You always are leading the way, even from behind.
Think of it like this, when you see a pack of wolves roaming, they are not I a single file line following the alpha, in fact they scattered around, but no matter where the alpha is, he is still leading the way and determining where they are going.
You can work a formal heel as your obedience moves along for when want your little buddy behind you.
Let us know if you have any other questions.
I Hope This Helps!
