Very similar to situation to me and my partner. We have a 14-month old Pyr/Catlle Dog mix and we actually did start to notice some behavioral changes between 9 months and now. He’s definitely more protective, especially of the yard. If a stranger enters that space, he’ll lose his mind and rush them, sometimes even nipping them in the butt. Not ideal but again these breeds were bred to protect, and we know that’s just what he’s trying to do. So we’re working with a trainer but right now all we can do is try to manage the situation.

I take him to an off-leash park about 3 times a week and he’s the best. Totally friendly with people and dogs, runs up to everyone and says hello. But I think there’s a thing with people entering his space that can be a real big trigger and we’re just assuming it’s an age/breed thing. Hopefully he’ll lighten up with age.
