To be fair, I'm pretty sure Complaint Investigator knows a fair bit about training dogs, especially as it pertains to aggression.
But yeah, that's resource guarding. Pyr's can be very independent, and function well like that when they got a job. Without a flock to watch over, or territory to defend, and after being a stray for 4 months or more, she's probably lost a fair bit of civility. I'd definitely find an experienced trainer to help ya work with her, or find her a home without other dogs.
In the best of circumstances they are stubborn as hell and you gotta be firm and consistent with any training.
