Is that ice on the ground?! Lucky.
I don't think it's an affectionate thing. I think the duck is obsessed with the dog in a bad way, like you thought.
The only time my ducks peck and pull at eachother is to get them out of the way or in an agressive manner.
I would be careful, the way the duck is bothering your dog, your dog is likely to snap at some point and kill that duck.
Pen it up or find a new home for it.
