That’s a bummer Ben. Some dogs have a dominant temperament, always wanting to be the alpha. Betty is that way. It can be a pain in the ass sometimes, but that temperament is IMO what helps her be so fierce and confident when hunting, doing things most female dogs won’t do. But... and it’s a big but... she is NOT the alpha around our household. And she knows it. It is understood. Now, bring a strange dog over to the house, and she will immediately size it up and express her dominance. There may even be some snarling and snapping for a minute. But that’s typically where it ends. Dogs like that have to be put in their place around the house. They aren’t always wired different... sometimes it’s just the way they are and the training needs to be tailored to that characteristic. More often than not, the dominant type dogs are very independent self-thinkers, usually requiring extra effort to have rock solid obedience. Your parents’ dog winning all those obedience competition awards leads me to believe it wasn’t a dominance issue and but more likely a “few screws loose” issue.
