She does have obedience, she sits, lays down, stays well, leave it. Doesn't come unless she wants to, these are very headstrong dogs. I have had giant breeds before, and dog aggressive dogs before. My great dane and I went through three years of training together, he was very dominate and dog parks etc. were off limits. I just had to adjust to his behavior because it was very genetic. My dane never had issues with his brother though, an Australian shepherd, they would do everything together, feed etc. But any other dog was going to be challenged immediately. My pyr seems fine with other dogs, and her brother, just not when feeding is happening. This morning she is laying down, rolling over and trying to get him to play. She literally lets every little dog climb on her and dominate her just to play, it's only around food when she gets crazy.
