I think she looks like a staffie to me. Those muscles
Staffies have super thick, muscular legs/build like that. Of course lots of dogs can but still. Her chest/front end look one to me too. Also very muscular and pretty wide. Not quite as wide as some but she’s a mix and also female. And the head also looks at least partly staffie/bully breed to me.
I agree the traits aren’t 100% obvious at first but look close enough and I do see it.
And she’s got the coloring and lean build of the Vizla.
That said, mixes are just that... mixes and the traits are not predictable or reliable to they can end up looking nothing like either parent or looking strongly like one breed they have the least percentage of, or looking like a totally different breed they’re not, etc. depending how the traits interact.
So even if she doesn’t necessarily look like a breed, she could still be it.
That said, what DNA test did you do? A lot of them are not reliable and have said purebreds are mixes before lol there’s only really two that are reliable and those are Embark and Wisdom Panel. Embark is pretty expensive but also tests for a bunch of genetic diseases and traits and stuff so worth it if you’re interested in that sort of thing. Wisdom Panel is fairly accurate and not too expensive.
Might be worth trying one of those if you are truly interested.
Either way, she is a beautiful dog.
