if you look at the body language of the bordeaux you will note there is no sign of fear coming from her she saw it as a game her tail never went between her legs at anytime.
Andrew;
Though her tail was not tucked, there are some signs of submission that you are overlooking. One way that dogs establish dominance is by "teeing up" or standing over another dog. Every time the Bordeaux attempts to evade the Neos, she comes over to you. That is her way of saying "I need help...please protect me." IMHO, the reason there was no escalation is that THE BORDEAUX AVOIDED IT BY SUBMITTING EVERY TIME. Though you didn't allow physical harm to the visitor, you seem oblivious to the fact that your pack is bullying her, and she wants nothing more than to escape.
I'm sure that everything did go smoothly subsequent to this initial filming. The Bordeaux quickly learned what she had to do to survive, that she was on her own, and that she could expect no help from the human pack leader. Dogs aren't dumb.
In the form of constructive criticism, you can learn alot from the body language of your visiting dogs. All three look to the videographer (you, the human pack leader) for leadership and direction, not your pack of canine peers. Even the little white puppy, who is not dominated or intimidated by your pack, looks directly at YOU when there is a pause and he's not sure what's going on.
Do you see the signs of avoidance and submission in Misty, the tiny black-and-white bull terrier in your first video? The folded ears, the tucked tail, the look of uncertainty in her eyes as she tries to creep closer to you for protection?
Your pack is fairly well behaved and they interact with each other very well, but you seem to be in denial about some aspects of their discipline. Do you notice all of the refusals in your OB sessions? I ask this because I see no corrections or do-overs; just repeated requests from you (almost like asking for compliance).
Most of the posters on this forum that have large packs, from what I've seen, talk about being the human pack leader, about dogs not being allowed to enforce rank or make corrections.
True enough, your pack sees you as the leader, but you seem to overlook their bad behavior at times, and you allow your visitors to suffer because of this. I sometimes have the same problem with my single, hyper, alpha dog. However, I have learned to pay attention, correct the situation, make amends to any I have offended, and remove one or all dogs to prevent further occurrences.
I hope this comes across as constructive. You have beautiful dogs that get along very well as a pack. They would be even better with a little more guidance in some of these situations, and a little more OB. In any event, this is all just MY opinion.
