Does anyone have any idea what breeds my dog could be?

This is my dog hazel and ever since we got her we have wondered what she is. Many people say she is a pit but we don't think she is. As you can see she has huge ears that stand up. She has six toes on her back feet and her fur is medium length and it's not very heavy or coarse almost like a lab. Her temperament is submissive and sweet. If anyone has any ideas I would love to hear them. Thank you!
