Awww, Dabney sounds adoreable!
All of my Poodles do the nose bop, and ever-so-gently when it's me, Luc, or the cat, they're bopping, not always so with each other! LOL They do it when they want me to go take a look at something, or when passing by, to get my attention, when they're pleased with something I've said or done, or just because! They each have their own style of nose-bopping, and I find the behavior so endearing.
