need help identifying my new pup

This puppy wandered into our yard a couple of days ago. We decided to adopt her right away. Although i know next to nothing about breeds, with the help of google we realized she looks somewhat like a boxer mix puppy because of the color pattern with darker nose and ears but we could be far from the truth, of course. Can somebody help me identify what else there may be going on? She is very feisty and playful 🙂
