I could maybe go for some beagle in there with the longer body, shorter legs. Don't see boxer or GP.
Yeah, I'm beginning to wonder if she even has any Pyrenees because she's just kinda dainty and like her bone structure in her legs and head isn't huge and bulky or thick legs etc. Like Gator. But then again Gator is a male. And yeah, probably not boxy/blocky enough for a Boxer either.
I do wonder if she's got some sort of hound the way she finds scents and goes running across the yard. But then she also gets distracted and runs back or elsewhere. Maybe that's just cause she's still new and there's lots of new and interesting scents out there? They are on a river and marsh so lots of interesting scents in the yard I'm sure. But still. And she is so smart.
