Welcome and thanks for rescuing those doggies. What I am realizing with interacting with dogs is that a lot of how they behave is determined by how I am feeling and my emotions when around them. If I am calm, relaxed and want to play with them, they can sense it and will respond accordingly. Conversely, if I am upset and stressed out, they know and usually will avoid me until I chill.
I have been practicing walking with my dogs recently. I know it sounds silly, but I do believe there is a right & wrong way to walk your dogs. It's common for dogs to get excited when they see other dogs on a walk. Hell, mine used to act like total fools when they saw another dog, jumping and carrying on. That would usually result in me getting tense and stressed because I knew what was coming. I would try to say their names and say "nonono" in that scenario but it only made things worse. They can sense the tension was increasing when I did that and they would go into "protective mode", lashing out at those who they believed was the cause of my tension.
I am practicing letting go of all of those negative emotions and feelings when other dogs are close to see how mine will respond. So far, I see a very noticeable change in their behavior because I am teaching myself not to get all tense and stressed in that situation. Perhaps your dogs are behaving similarly because of it?
It's taken me over 40 years to finally wake up and be more self aware. I think a lot of people don't realize what they say, feel or do at times throughout the day because we're mostly wrapped up in so much. It's definitely not easy at all to let go of the stress because we have grown used to reacting in a specific way in specific scenarios.
Or I could be way off and your dogs are just nuts
In either event, I hope this might help out a bit. Dogs act more like us than we realize sometimes.
