Oh my... The dog is territorial while in her yard, looks at you intensely and climbs on people. WHY THE HECK would that make you think its right to put her down? I've known dogs who climb on people, or crawl into their laps, at about a half mile per hour, looks like they're trying not be seen, it's who they are... As for staring, all of my dogs stare at me. I think thats a load of bull when every says it's a dominance thing. Bulldogs must be dense because 90% of the ones I've met will stare at you until you give them something to do or give them attention. They're just watching you. When you look at your dogs, do you look at their tail? NO. You look to their face. Dogs seem to be the same. They look at your face for a variety of reasons.
In fact, climbing slowly is being polite... Would you rather she bounced up on them and tried clawing her way to their face to give attention?

Has she ever shown real aggression towards human who was in her yard/house or out of it when she was out?

My GSD, and my pom will bark and run up and down like they're nuts, but are fine when the person comes in.

She hasn't even had time to settle into your home... It could take months, and MONTHS for her to settle down and really start to shine and show you who she is.

Please, take this girl back...
