Usually, with working bred Border Collies, it is not a dominance issue towards people. They have been bred for years to want to please; the issue is usually getting and keeping their focus on what you want when their young minds are so easily distracted by so much stimuli.
Our first Border Collie was from working lines known to be "hard", meaning they want to do things their way. But as a pup he was one of the brightest we've ever hard and wanted to please. He learned many commands including "go to bed" (go into your crate). One day while my sister was visiting "go to bed" was said during normal conversation (not directed at our pup); when he heard this he hung his head and slinked off to his crate. It's this quick to learn characteristic that gets many new owners into trouble; when their mind is not occupied they will find a "problem to solve" which you may not like.
