Help my guess my dog's true breed?

[JulieNKC]

I honestly think she is just pet quality chi. I have seen them with floppy ears, wrong coats, oversized etc. Which in those too, there may be something else, but if it is it's a little way back, like a great grandparent was a mix, but the rest were pure. She's def not half and half anything. Her face and coloring are almost identical to my Angelina. Angelina doesnt have the white and she is smooth coated, but she has that sable and tan pattern.

Here's Helmsley:
