What do yall think my lil piglet is

Hi all! This is my lil creature we called Poppy. She’s about six years old now, but I found her at my ex boyfriend’s 21st bday years ago. I watched a car dump her in an HEB hand held basket by a Taco Bell when she was predicted about 2 weeks old. We thought she was a rottie, she grew up looking like one. But one day she just kinda stopped growing, especially her head lol. I’m a dog groomer so I feel like usually I am pretty good at guessing breeds but she has me stumped. I wanna see y’all’s guesses! Doing a DNA test soon.
