When you have 2 dogs is it possible that neither of them is dominant over the other one?

Hi Cindy! I have watched the course how to establish pack structure and have a question regarding dog behaviour during play. I am researching as much as i can on the subject of dog body language and signs that could prevent a dog fight. In the situation when a female and male that meet on a regular basis, have structured walks and play- is it possible that neither of them be dominant over another? GSD Female is 3 yo and GSD male is 4yo, they no longer play as much with each other when they meet and prefer fetch game with balls and calm pack walks. I always thought my female is dominant but after watching explanation of signs during play im no longer sure of that. I have a video of them playing . Thank you so much for excellent course I agree with everything that’s discussed and i feel like every new dog owner must have it, it would be much less reactive dogs on the walks and more happy owners:) thank you!

Thank you for your reply! I also always supervise dog interacting as well and interrupt if needed as i have seen situations where things get escalated. Even with the dogs that know each other.
